Abstract:
An objective is to provide a developing roller possessing a surface layer capable of suppressing the residual potential during repetitive use with no damage of interlayer adhesiveness, preventing toner leakage and contaminations caused by adhesion matter on the surface, and preventing developing unevenness because of even toner electrification; and also to provide an image forming method employing the developing roller. Also disclose is a developing roller possessing a conductive shaft, and a resin layer provided around an outer circumferential surface of the conductive shaft, wherein the resin layer possesses a surface layer containing a silicone copolymer resin as a principal component and a layer containing a polyamide resin as a principal component, that is provided immediately below the surface layer.
