Abstract
A process cartridge detachably mountable to a main assembly of an image forming apparatus, includes an electrophotographic photosensitive member; charging means for charging the photosensitive member;
developing means for developing a latent image formed on the photosensitive member; a cartridge frame; a grounding contact for electrically grounding to the main assembly; a charging bias contact for receiving charging bias voltage from the main assembly to be applied to the charging means; a developing bias contact for receiving a developing bias voltage to be applied to the developing means; a detection contact for permitting detection of mounting of the process cartridge to the main assembly; wherein the grounding contact, the charging bias contact, the developing bias contact and the detection contact are provided on one end, with respect to a direction of an axis of the photosensitive member, of the process cartridge in an exposed state; and wherein the developing bias contact takes a bottommost position, and the charging bias contact takes a topmost position, among the contacts in a vertical direction when the process cartridge is mounted to the main assembly; and wherein the detection contact takes a most upstream position, and the grounding contact takes a most downstream position, among the contacts, with respect to a mounting direction of the process cartridge to the main assembly.
