ABSTRACT:
A process cartridge detachably mountable to a main assembly of an image forming apparatus includes an electrophotographic photosensitive member, a guiding member, a charging device for charging the photosensitive member, a developing device for developing a latent image formed on the photosensitive member, a cartridge frame, a grounding contact for electrically grounding the photosensitive member to the main assembly when the process cartridge is mounted to the main assembly, a charging bias contact for receiving charging bias voltage from the main assembly to be applied to the charging device when the process cartridge is mounted to the main assembly, a developing bias contact for receiving a developing bias voltage to be applied to the developing device when the process cartridge is mounted to the main assembly, a detection contact for permitting detection of mounting of the process cartridge to the main assembly to provide notification to the main assembly that the process cartridge is mounted to the main assembly. The grounding contact, the charging bias contact, the developing bias contact and the detection contact are provided on a side surface of the cartridge frame.
