PROBLEM TO BE SOLVED: To provide a conductive roll for an electrophotographic apparatus, which has low hardness and excels in an elastic recovery factor, and excels in rupture strength further than the conventional one.SOLUTION: In the conductive roll 10, an elastic layer 14 formed on an outer periphery of a shaft body 12 includes crosslinking body of composition containing (A) base polymer having an alkenyl group and urethane bond in molecular structure having at least one backbone selected from polyoxyalkylene backbone, polyester backbone and polycarbonate backbone, (B) hydrosilyl crosslinking agent and (C) hydrosilylation catalyst. It is desirable that the composition contains a conductive agent such as an ion conductive agent. Further, it is desirable that (A) component is polymer that is liquefied at room temperature. |
