Abstract
An elastic rotatable member, includes an elastic rubber layer, a surface layer of resin formed on the elastic layer, wherein the surface layer is provided by applying resin material together with liquid to a surface of the elastic rubber layer and sintering the resin material by heating the resin material up to a sintering temperature thereof while keeping the elastic rubber layer below its durable temperature, wherein the heating is effected by dielectric heating to heat the resin material up to a higher temperature than that of the rubber layer.
