Abstract
A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus including a driving shaft having a rotational force applying portion by moving in a direction substantially perpendicular to an axis of the driving shaft. The cartridge includes an electrophotographic photosensitive drum, a coupler engageable with the rotational force applying portion to receive a rotational force for rotating the drum and taking transmitting, pre-engagement, and disengaging positions, and a regulator regulating an inclination angle of the coupler. During cartridge mounting, the coupler moves from the pre-engagement to the transmitting position to oppose the driving shaft, and during cartridge dismounting, the coupler moves from the transmitting to the disengaging position to disengage from the driving shaft.
