摘要： A roller for office automation equipment which does not suffer from impairment of a cross-linking reaction or occurrence of a delay therein, is excellent in permanent set resistance and low-temperature bleedability, and permits achievement of a low hardness. The roller for office automation equipment comprises a base rubber layer (2), an intermediate layer (3) and a surface layer formed (4) in this sequence on an outer peripheral surface of a shaft (1), wherein the base rubber layer is formed of a liquid rubber composition containing the following constituents (A-D): (A) a liquid rubber, derived from at least one of butadiene and isoprene, and having a structural unit (α) having an alkenyl group on the side chain thereof; (B) a hydrosilyl cross-linking agent; (C) a hydrosilylation catalyst; and (D) a mineral oil containing not more than 0.31wt.% sulfur.
