ABSTRACT:
A fixing roll for electrophotography having a surface layer of a cured room-temperature-vulcanizing silicone rubber composition comprising a mixture consisting of two diorganopolysiloxanes, one of which is terminated at the chain ends with silanol groups and has a relatively high viscosity, and the other of which is terminated at the chain ends with trialkyl silyl groups and has a relatively low viscosity, an alkoxysilane or a partial hydrolysis-condensate thereof as the crosslinking agent, a metal salt of an organic acid as the reaction catalyst, and three kinds of inorganic fillers, namely, calcium carbonate, iron oxide, and titanium dioxide, and containing substantially no siliceous fillers. The fixing rolls have excellent properties including, in particular, the ability to provide a long copy-life to electrophotographic copying machines.
