Abstract
A process cartridge usable with an electrophotographic image forming apparatus, the process cartridge includes i) an electrophotographic photosensitive drum rotatable about an axis and having a photosensitive layer at its peripheral surface; ii) process means actable on the drum; iii) a coupling member for receiving an external force for rotating the drum, wherein the coupling member is capable of taking a first angular position for transmitting the external force to the drum, a second angular position inclined away from the axis of the drum from the first angular position, and a third angular position away from the axis of the drum from the first angle position; and iv) a regulating portion for regulating an inclination angle of the coupling member such that downward inclination angle of the coupling member is smaller than an inclination angle of the coupling member when the coupling member is at the second angular position.
