Abstract:
To provide a conductive member for an electrophotographic machine that is capable of preventing hardening degradation of a surface layer that is caused by an ionic conductive agent contained in a conductive rubber elastic body layer, allowing the surface layer to be improved in durability.A conductive member 10 for an electrophotographic machine includes a conductive rubber elastic body layer 14 containing crosslinked rubber and an ionic conductive agent, and a surface layer 16 provided on an outer periphery of the conductive rubber elastic body layer 14, wherein the surface layer 16 contains a polymer and polyphenol. Examples of the polyphenol include a tannin, gallic acid, ellagic acid, pyrogallol, catechin, and chlorogenic acid.
