ABSTRACT:
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, includes an electrophotographc photosensitive drum; a developlng member for developing an electrostatic latent image formed on the electrophotographic photosensitive drum with a developer; charging member for electrically charging the drum; a drum frame supporting the charging member and the drum; a developer accomodation frame having a developer accomodating portion for accomodating the developer; a supporting frame supporting the drum frame and the developer accomodation frame adjacent one logitudinal end of the drum; a developing bias contact, provided on the supporting frame, for receiving a developing bias voltage applied to the developing member from the main assembly of the apparatus when the process cartridge is mounted to the main assembly of the apparatus; and a charging bias contact, provided on the supporting frame, for receiving a charging bias applied to the charging member from the main assembly when the process cartridge is mounted to the main assembly.
