    Abstract: A developing roller includes a roller main body disposed to face, without contact, an outer circumferential surface of an image carrier. In the roller main body, a boehmite layer has been formed on an outer circumferential surface of a base body that is made of a metal including aluminum, by a surface treatment by a boehmite method, and a resin coat layer has been formed on a surface of the boehmite layer, the resin coat layer being made of a resin material having electric conductivity.

    Abstract: A developing device supplies a developer to a photosensitive drum, which has a cylindrical shape, and is rotatable around an axis thereof for forming an electrostatic latent image on the circumferential surface thereof. The developing device is provided with a developing roller. The developing roller is disposed to face the photosensitive drum, and has a cylindrical shape. The developing roller is rotatable around an axis thereof for carrying a developer on the circumferential surface thereof. The developing roller is provided with a small diameter portion. The small diameter portion is a part of the circumferential surface of the developing roller. The small diameter portion extends from an axial end of the developing roller axially inward by a predetermined length, and has an outer diameter smaller than an axially middle portion of the developing roller.
