Summary:PROCESS CARTRIDGE, ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS ELECTROGRAPHIC PHOTOSENSTIVE DRUM UNIT A process cartridge which is detachably mountable to a main assembly of an electrophotographic 5 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, includes i) an electrophotographic photosensitive drum rotatable 10 about an axis; ii) process means actable on the drum; iii) a coupling member engageable with the rotational force applying portion to receive a rotational force for rotating the drum, the coupling member being capable of taking a rotational force transmitting 15 angular position for transmitting the rotational force for rotating the drum to the drum, 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 20 angular position in which the coupling member is inclined away from the axis from the rotational force transmitting angular position; and iv) a regulating portion for regulating an inclination angle of the coupling member such that downward inclination angle 25 of the coupling member is smaller than an inclination angle of the coupling member when the coupling member is at the pre-engagement angular position, wherein in 7274655vl mounting the cartridge to the main assembly by moving the cartridge in the direction, the coupling member moves from the pre-engagement angular position to the rotational force transmitting angular position to 5 oppose the driving shaft, and in dismounting the cartridge from the main assembly by moving the cartridge in the direction, the coupling member moves from the rotational force transmitting angular position to the disengaging angular position to 10 disengage from the driving shaft. 7274655vl
