Abstract
A method for making a developer roll by molding a metal shaft with a conductive or semi-conductive soft rubber forming a rubber core and a coating deposited on the soft rubber core wherein the coating has a conductive agent. The outer surface of the soft rubber core is modified to form an —OH rich surface layer before the coating is deposited onto the outer surface of the rubber core to chemically bond therein.
