Description
Technical Field
The invention relates to the technical field of printing consumables, in particular to a processing box.
Background
An electrophotographic image forming apparatus such as a laser printer is an apparatus that forms an image on an image forming medium such as paper by using an electrophotographic principle at least through the processes of charging, exposing, developing, transferring, fixing, and cleaning.

The process cartridge is placed in the image forming apparatus, and a driving member of the process cartridge is rotated with a transmission member of the image forming apparatus by coupling with the transmission member of the image forming apparatus, thereby effecting a circumferential rotational movement of a developing unit in the process cartridge. The conductive contact of the conductive end of the processing box is contacted with the conductive position on the imaging device, so that the developing component in the processing box is provided with positive voltage or negative voltage according to the structural characteristics, and the toner in the toner bin supplies powder to the photosensitive drum under the action of the electric field force of the developing roller and other components, thereby developing the photosensitive drum, and then transferring the toner to paper through transfer printing. When the toner in the process cartridge is exhausted, the process cartridge needs to be detached from the image forming apparatus.
The driving component of the existing processing box adopts a driving connection structure of a ball type universal joint, and in the transportation process, a driving component is easy to separate, so that a photosensitive drum or a developing roller cannot receive a driving force, and the processing box cannot be normally used.
