The image forming apparatus generally supplies toner using a toner cartridge detachably mounted therein. In addition to containing toner, the toner cartridge is usually integrated with developing members such as a developing roller, a toner feeding roller, and a toner discharging knife, wherein the toner feeding roller is used for feeding toner to the developing roller to form a toner layer, the toner discharging knife is used for adjusting the thickness of the toner layer on the developing roller, and the developing roller uses the toner carried thereon to develop the electrostatic latent image on the photosensitive element. In the development process, the developing roller, the toner feeding roller, etc. generally need to be energized to bring the toner to a desired charge. The developing members are respectively electrically connected with conductive contacts provided at conductive ends of the toner cartridge, and after the toner cartridge is mounted to the image forming apparatus, the conductive contacts are respectively connected with output electrical contacts in the image forming apparatus to receive different voltages from the image forming apparatus.
Referring to fig. 1, fig. 1 is a block diagram of a toner cartridge detachably mountable to an image forming apparatus as disclosed in the prior art. The toner cartridge 1 comprises a cartridge body 14, a toner feed roller (not labeled), a developing roller 11, a toner feed electrode 13 and a developing electrode 12, the developing electrode 12 and the toner feed electrode 13 protrude outwards relative to the cartridge body 14, that is, the developing electrode 12 comprises a developing protrusion 121, the toner feed electrode 13 comprises a toner feed protrusion 131, the toner feed protrusion 131 and the developing protrusion 121 protrude outwards relative to the cartridge body 14 so that a developing roller power supply contact 2 of the image forming apparatus is in contact with the developing protrusion 121, a toner feed roller power supply contact 3 of the image forming apparatus is in contact with the toner feed protrusion 131, and the toner feed electrode 13 and the developing electrode 12 are supplied with power through the toner feed protrusion 131 and the developing protrusion 121 so that the developing electrode 12 and the toner feed electrode 13 apply a developing bias and a toner feed bias to the developing roller 11 and the toner feed roller of the cartridge 1, thereby transferring toner from the toner feed roller to the developing roller 11 is realized under the influence of a potential difference between the developing roller 11 and the toner feed roller at a developing position. At the same time, the toner is supplied to the photosensitive drum by the electric field force of the developing roller 11 and other members, thereby developing the photosensitive drum, and then transferring the toner to the paper by transfer.
The developing electrode 12 and the powder feeding electrode 13 are injection molding pieces containing conductive materials, and the conductive materials in the injection molding pieces are difficult to uniformly distribute, so that the conductive ends of the toner cartridge 1 are unstable in electrical connection with the imaging equipment, poor conduction is caused, the voltage difference between the developing roller 11 and the powder feeding roller is little, and the transfer of the toner on the powder feeding roller to the developing roller 11 is influenced. The toner transferred to the developing roller 11 is small, and the developing roller 11 supplies toner to the photosensitive drum to cause a printing failure. Meanwhile, the conductive material is added into the injection molding piece, so that the high polymer material has high cost, and the cost of the carbon powder box 1 is greatly increased.
