<p>A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus includes an electrophotographic photosensitive drum (7); charging means for electrically charging the electrophotographic photosensitive drum; developing means for developing a latent image formed on the electrophotographic photosensitive drum; grounding contact (119) for electrically grounding the electrophotographic photosensitive drum to the main assembly of the apparatus when the process cartridge is mounted to the main assembly of the apparatus; a developing bias contact (120) for receiving, from the main assembly, a developing bias (121) to be applied to the developing means when the process cartridge is mounted to the main assembly of the apparatus; a charging bias contact for receiving, from the main assembly, a charging bias to be applied to the charging means when the process cartridge is mounted to the main assembly of the apparatus; a cartridge coupling member for receiving, from the main assembly, driving force for rotating the electrophotographic photosensitive drum, the cartridge coupling member being engaged with a main assembly coupling member of the apparatus when the main assembly coupling member is rotated after the process cartridge is mounted to the main assembly of the apparatus, wherein the cartridge coupling member is disposed substantially coaxially with the electrophotographic photosensitive drum above-described one longitudinal end of the electrophotographic photosensitive drum; wherein the grounding contact (119), developing bias contact (121) and charging bias (122) are disposed above-described a longitudinal end of the electrophotographic photosensitive drum which is opposite from the longitudinal end where the cartridge coupling member is disposed; the developing bias (121) contact is disposed at one lateral side; the charging bias contact (120) is disposed at another lateral side; and the grounding contact (119) is disposed substantially coaxially with the electrophotographic photosensitive drum. <IMAGE></p> |
