PROBLEM TO BE SOLVED: To provide a conductive roll having small fluctuation width of electric resistance caused by environmental changes such as the temperature and the humidity, and voltage change, and causing no blooming, etc. SOLUTION: This conductive roll is formed with a conductive elastic body layer in the outer circumference of a shaft body and a resistance adjustment layer in the outer circumference of the conductive elastic body layer. The resistance adjustment layer is composed of the following (A)-(D) components as the essential components and formed of a rubber component with the (C) component set to 5-50 pts.wt. relative to the total amount of the (A) and (B) components, 100 pts.wt. (A) Epichlorohydrin rubber. (B) Acrylonitrile-butadiene rubber. (C) Carbon black. (D) Ionic conduction agent. |
