Process cartridge and electrophotographic image forming apparatus

摘要

A process cartridge (15) which is detachably mountable to a main assembly of an electrophotographic image forming apparatus includes an electrophotographic photosensitive drum (11); a developing member (18) for developing an electrostatic latent image formed on the electrophotographic photosensitive drum; a developer accommodating portion for accommodating the developer to be used by the developing member to develop the electrostatic latent image; a developer feeding member (114) for feeding the developer accommodated in the developer accommodating portion toward the developing member; a first driving force transmitting means (103) for transmitting to the electrophotographic photosensitive drum a driving force which is received from the main assembly of the apparatus to rotate the electrophotographic photosensitive drum when the process cartridge is mounted to the main assembly of the electrophotographic image forming apparatus; a second driving force transmitting means (104) for transmitting to the developer feeding member (114) a driving force received from the main assembly of the apparatus to rotate the developer feeding member when the process cartridge is mounted to the main assembly of the electrophotographic image forming apparatus, wherein the second driving force transmitting means is independent from the first driving force transmitting means.
