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.
