ABSTRACT:
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, includes a first frame; a second frame coupled with the first frame for rotation about a shaft relative to each other; a first electrical contact, provided in the first frame, for receiving, from the main assembly, a bias voltage to be supplied to the charging member; a second electrical contact, provided in the second frame, for receiving, from the main assembly, a bias voltage to be supplied to a developing member, a developer feeding member and a regulating member; and a third electrical contact, provided in the first frame coaxially with the drum, for electrically grounding the drum to the main assembly. The first and second contents are disposed at one end of the first frame and the second frame, respectively, and the third contact is disposed at the other end of the first frame, and wherein the contacts are disposed such that, the first contact takes a higher position than the second.
