Abstract:
A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus including a positioning portion, a rotatable urging member taking an urging position for urging the cartridge to the positioning portion, and retracted and stand-by positions. The cartridge includes an electrophotographic photosensitive drum, a process device actable on the drum, a positionable portion, a displacing portion moving the urging member from the stand-by to the retracted position by contacting a portion-to-be-displaced disposed at a position remoter from the rotation axis of the urging portion than the urging portion when the cartridge advances along an axial direction of the drum in the main assembly, the displacing portion moving the urging member to the retracted position by contacting the urging member when the cartridge advances in the main assembly, and an urgable portion urgable by the urging portion when the cartridge is set in the main assembly.
