Abstract

A developer-carrying member to be installed in an electrophotographic developing device for carrying and conveying a developer along a surface thereof, is formed of a substrate, and an intermediate electroless plating layer and an electroplating layer disposed in this order on the substrate. As a result of the electroless and electro double plating layer structure, the developer-carrying member is provided with a wear-resistant surface which has an appropriate degree of roughness suitable for conveying the developer thereon and is yet free from minute projections and cracks undesirable from the viewpoint of continuous image forming performances.
