摘要:
An objective is to provide a developing roller in which increase of residual potential is inhibited during repetitive operation without deteriorating interlayer adhesion, and prepared is a layer immediately below the surface capable of preventing fog caused by toner scattering, accompanied with a surface layer capable of preventing stains formed from foreign matters adhered to the surface, as well as preventing image unevenness since toner electrification is even under the presence of appropriate elasticity, and also to provide a image forming method employing the developing roller. Disclosed is a developing roller possessing an elastic layer made of silicone rubber provided around a conductive shaft, and a plurality of resin layers further provided on the elastic layer, wherein an outermost surface layer among the resin layers comprises silicone copolymerization polyurethane; and a layer immediately below the surface layer comprises a polyurethane resin-silica hybrid.
