Abstract:
A process cartridge includes: a developing unit; a drum unit; an urging member; and an electrically-conductive member. The developing unit includes a developing roller. The drum unit includes a photosensitive drum. The developing unit is pivotally movable relative to the drum unit about a pivot axis extending along the developing roller. The urging member is configured to urge the developing roller toward the photosensitive drum. The electrically-conductive member is provided at the developing unit and configured to apply voltage to the developing roller. The electrically-conductive member is made of an electrically-conductive resin. The electrically-conductive member includes a contact portion configured to contact an electric contact provided at an image forming apparatus. The pivot axis and the contact portion define a first distance therebetween. The pivot axis and the urging member define a second distance therebetween. The first distance is smaller than the second distance.
