Abstract
An objective is to provide a developing roller in which increase of residual potential is inhibited during repetitive operation without deteriorating adhesion to an elastic layer, scattering and leakage of toner are prevented, appropriate elasticity is exhibited and a resin layer capable of preventing uneven charging of toner and image unevenness is prepared, 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 resin layer further provided on the elastic layer, wherein the resin layer contains polyurethane resin-silica hybrid as a principal component.
