PROCESS CARTRIDGE, ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS AND ELECTROGRAPHIC PHOTOSENSITIVE DRUM UNIT

摘要

A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The process cartridge includes a coupling member engageable with a rotational force applying portion to receive a rotational force. The coupling member is capable of taking a rotational force transmitting angular position for transmitting the rotational force, a pre-engagement angular position in which the coupling member is inclined away from the axis from the rotational force transmitting angular position, and a disengaging angular position in which the coupling member is inclined away from the axis from the rotational force transmitting angular position.
