Developing cartridge

摘要

A process cartridge, which includes a developing cartridge and a photosensitive cartridge for use with an image forming apparatus including a driving force output part and a feeding part, is provided. The developing cartridge includes a developer carrier, a first electrode provided at one side thereof, and a driving force receiving part provided at another side thereof and aligned with the first electrode such that the driving force receiving part overlaps the first electrode in a side view. The photosensitive cartridge, to which the developing cartridge is removably mounted, includes a photosensitive member, and a second electrode that contacts the first electrode when the developing cartridge is mounted in the photosensitive cartridge and that contacts the feeding part when the photosensitive cartridge is mounted in the image forming apparatus. The first electrode is pressed toward the driving force receiving part by contact with the second electrode.
