Abstract
A process cartridge and an electrophotographic image forming apparatus. The process cartridge includes a cartridge body, a photosensitive drum having a first axis, and a driving force receiving member having a second axis. The photosensitive drum is rotatably supported between two end walls of the cartridge body, and the driving force receiving member has a head portion and a shaft portion. The driving force receiving member is connected to an axial end of the photosensitive drum through an Oldham coupling; a rotation angle limiting mechanism is disposed between the driving force receiving member and the photosensitive drum; and the driving force receiving member is movable in a direction perpendicular to the first axis and rotatable around the second axis such that the second axis is either co-axial or parallel with the first axis.
