摘要： A conductive roll available at low cost and superior both in moldability and compression set and having small dispersion or fluctuation in electrical resistance includes a shaft and a base rubber layer formed on a peripheral surface of the shaft, the base rubber layer formed of a composition containing the following components (A) to (C): (A) a liquid polymer having a structural unit (.alpha.) derived from at least one of butadiene and isoprene and having an alkenyl group in a side chain thereof; (B) a hydrosilylation crosslinking agent; and (C) a hydrosilylation catalyst. In the conductive roll the alkenyl group of the structural unit (.alpha.) in the liquid rubber (component A) becomes a crosslinking site and is present in a molecule thereof as a so-called pendant form so that the base rubber layer as a crosslinked mold comes to have a dense net structure due to the effects by the hydrosilylation crosslinking agent (component B) and the hydrosilylation catalyst (component C), thereby to obtain good copied images.
