Patent ID: 8135300

Claim:
A process cartridge for use with an image forming apparatus which comprises a driving force output part and a feeding part, the process cartridge comprising: a developing cartridge comprising: a developer carrier; a first electrode provided at one side of the developing cartridge, the first electrode being configured to apply a bias to the developer carrier; and a driving force receiving part provided at another side of the developing cartridge, the driving force receiving part being configured to receive the driving force from a driving force output part to drive the developer carrier, and the driving force receiving part being aligned with the first electrode such that the driving force receiving part overlaps the first electrode when viewed from a side of the developing cartridge; and a photosensitive cartridge which is configured to be removably mounted within the image forming apparatus, the developing cartridge being configured to be removably mounted to the photosensitive cartridge, the photosensitive cartridge comprising: a photosensitive member; and a second electrode that is positioned to contact the first electrode when the developing cartridge is mounted in the photosensitive cartridge, and to contact the feeding part when the photosensitive cartridge is mounted in the image forming apparatus, wherein the first electrode is configured to be pressed toward the driving force receiving part by contact with the second electrode, wherein a first pressure under which the driving force receiving part is pressed toward the first electrode by the driving force output part is smaller than a second pressure under which the first electrode is pressed toward the driving force receiving part by the second electrode.
