    摘要: A developing roller supports a one-component developer on a surface thereof in the form of a thin layer, and is brought in contact with or in proximity to an image forming body in such a state, to supply the developer on a surface of the image forming body, thereby allowing a visible image to be formed on the surface of the image forming body. The developing roller includes: an elastic layer having an ionically conductivity whose surface is imparted with a resin component having a high resistivity. Thus, if R1 is a resistance of the roller in a stationary state and R2 is a resistance of the roller in a rotational state, a relationship of R1>R2 is established. With this developing roller, it is possible to obtain a high quality image and a high gradient.
