ABSTRACT:
A process cartridge is detachably mountable to the main body of an electrophotographic image forming apparatus for forming an image on a recording medium. The image forming apparatus has a twisted hole, the cross-section of which has a plurality of corners. The process cartridge includes an electrophotographic photosensitive drum, a developing roller for developing an electrostatic latent image formed on the electrophotographic photosensitive drum, and a driving-force transmitting part provided on one lengthwise end of the electrophotographic photosensitive drum and having a twisted protrusion to be fitted in the hole and whose cross-section has a plurality of corners. The process cartridge also includes a shaft portion supported by a bearing portion, and a gear portion for transmitting a driving force to the developing roller, the shaft portion and the gear portion overlapping each other in the axial direction of the electrophotographic photosensitive drum.
