2. Description of the Related Art In an electrophotographic apparatus, a recording medium on which a latent image is formed is developed with toner, and the visualized toner image is transferred to a transfer material such as paper. Therefore, when the above recording medium is used repeatedly, it is necessary to remove the residual toner in the transfer unit and the deposits such as paper powder adhering at the time of transfer. This type of apparatus requires cleaning of a fur brush, a magnet roll or a blade. There is a cleaning device used as a body, and has a transport member that transports the toner collected by the cleaning device to a collection container. Further, the cleaning body of the cleaning device has a function of contacting and separating from the surface to be cleaned at a predetermined timing in order to improve the function, but the cleaning body for collecting the toner is housed inside the case. It is configured. As such a cleaning device, there is a cleaning device as described in JP-A-61-62092.

In this conventional apparatus, the toner collected by the cleaning body is transported in one direction by a transport member and transported to a recovery container. Therefore, the recovery container must be disposed outside the image forming section. In order to transport the toner to that point, only the transport member of the cleaning device is configured to be long in the transport direction. Therefore, it was necessary to largely escape the peripheral device in order to attach and detach the cleaning device. Further, the cleaning body of the cleaning device has a function of contacting and separating from the surface to be cleaned at a predetermined timing for improving the function, but has a complicated configuration in order to make the cleaning body housed inside the case movable. Or the inside of the case has a problem that the collected toner flies in a mist and the entire cleaning body is contaminated. In recent years, demands for user maintenance have increased, and it has been demanded that units having a short life can be easily replaced and that the units are not soiled at the time of replacement. In the past, it was necessary to replace the entire cleaning device.

The cleaning device can be divided into a unit having a cleaning member and a unit having a conveying member, and the unit having the conveying member is fixed to the main body, and the unit having the cleaning member can be detachably mounted. The user can easily replace only the cleaning body having a short life. Here, the transport member is configured to be long in the transport direction to transport the collected toner to the collection container, and is connected to the collection device.
The attachment and detachment of this unit is very complicated, and it is very important to leave this unit in the main body. In addition, the unit of the transport member has a longer life than the cleaning body, and has conventionally been discarded in accordance with the life of the cleaning body. However, according to this method, only the cleaning body can be discarded, and there is a great cost advantage. Further, in order to attach and detach the cleaning device, it is necessary to largely escape the peripheral device.

Next, the operation will be described. Recording medium 1
The upper residual toner 2 is negatively charged,
By applying a positive charge from a power source 23 connected to the conductive brush 11, the residual toner 2 is attracted to the brush 11 and the recording medium 1 is cleaned. The residual toner 2 on the brush 11 is collected by the collection roller 1 by the rotation of the brush 11.
After being transported to the point of contact with the brush 2, the power supply 24 connected to the collection roller 12 applies a charge larger than the positive charge applied to the brush 11 so that the brush 11
From the toner to the collection roller 12 and the brush 1
1 is cleaned. A blade 13 is pressed against the collection roller 12, and the collection roller 12 is cleaned by the rotation of the collection roller 12. Thereafter, the residual toner 2 falls onto the transport member 17, is transported by the rotation of the transport member 17, and is deposited on the collection container 40. The above operation completes the cleaning operation.

Here, according to the experiment, the brush 11 is about 100,000 sheets in terms of recording paper A4 due to loosening or falling down of the flock, and the blade 13 pressed against the collecting roller 12 is a wear-resistant material such as urethane. However, in printing on tens of thousands of sheets in terms of recording paper A4, poor cleaning due to abrasion of the edge portion occurs. On the other hand, if the attention is paid only to the bearing structure of the rotating part, about hundreds of thousands of conveyance members will operate normally. Conventionally, components having different lifespans are integrally formed as described above, and depending on the life of the blades 13, it is necessary to discard the entire cleaning device 10 or replace the blades by a specially trained service person.

Further, during color printing, the brush 11 of the cleaning device 10 is always kept in contact with the print medium 1 when developing a plurality of times and then transferring and cleaning the residual toner 2 or when not operating. In this case, the flocking of the brush 11 may be deformed, so that the brush 11 may need to be retracted. Therefore, the unit 16 having the cleaning member is moved by the eccentric cam 25 as shown by 16 ', and the brush 11 is detached from the recording medium 1. Here, by supporting the unit at the center of rotation of this operation, the support can also be used as the axis of the collection roller 12 and the gears 35 and 36 can be positioned with high precision during the connection. In the related art, only the brush 11 inside the case 14 is driven, so that the configuration is complicated, or the entire cleaning device 10 is retracted. However, the configuration described above can be easily configured.

Further, in the same manner as in the first embodiment, during color printing, development is performed on the print medium 1 a plurality of times, and then transferred,
When the residual toner 2 is to be cleaned, or when the blade 50 of the cleaning device 10 is constantly brought into contact during non-operation, the blade 50 may be deformed. Therefore, the unit 53 having the cleaning member is moved by the eccentric cam 25 as shown by 53 ', and the blade 50 is detached from the recording medium 1. Here, by supporting the unit at the rotation center of this operation, the support can also be used as the rotation axis of the blade 50.
Conventionally, the blade 50 is disposed inside the transfer case 56, so that the cleaning device 10 is contaminated by the collected toner and the blade 50 is driven, or the cleaning device 10 is entirely evacuated. It has become possible to make the configuration simpler.
