Abstract
A process cartridge is mountable to an image forming system and includes an image bearing member; a developing bias contact for applying a developing bias to a developing device; an earthing contact for earthing the image bearing member; and a charging bias contact for applying a charging bias to a charging device. The developing bias contact, the earthing contact, and the charging bias contact are arranged in an area corresponding to an end portion of the image bearing member in a longitudinal direction of the image bearing member, such that (i) the developing bias contact is arranged at a first side of the image bearing member in a direction orthogonal to the longitudinal direction of the image bearing member, and (ii) the earthing contact and the charging bias contact are arranged at a second side of the image bearing member in the orthogonal direction.
