There is a developing roller having a low compression permanent strain without contaminating a photosensitive drum and deteriorating toners. The developing roller (1) comprises a shaft (2), an elastic layer (3) formed on an outer periphery of the shaft (2) and a surface coating layer (4) formed on an outer peripheral face of the elastic layer (3), in which the surface coating layer (4) comprises a urethane resin formed by crosslinking a lactone-modified polyol with a polyisocyanate. The urethane resin is preferable to be formed by crosslinking the lactone-modified polyol with two or more kinds of polyisocyanates.
