PURPOSE:To provide a conductive roll with which proper initial resistance is obtd., proper electric resistance can be maintained even when used for a long time, and good images can be obtd. CONSTITUTION:This conductive roll is produced by forming a conductive elastic layer 27 around the core metal 26, forming a softening agent-preventing layer 28 essentially comprising N-methoxymethylate nylon around the layer 27, then forming a resistance controlling layer 29 around the layer 28, and further forming a protective layer 30 essentially comprising N-methoxymethylate nylon as the outermost layer around the layer 29. The resistance controlling layer 29 consists of a compd. essentially comprising components (A) to (C). (A) Epochlorohydrin-ethylene oxide copolymer, (B) hydrogenated nitrile rubber, and (C) ionizing conductive agent. |
