ABSTRACT:
Silicone rubber is employed as an outer coating material on a fuser member and is applied to the base member by means of a novel construction which prevents the separation of the outer silicone rubber coating from the roll even when silicone oil is applied thereto. The fuser member comprises a base member, a layer of a heat-resistant resin formed on the base member and a layer of a silicone rubber formed on the heat-resistant resin layer, the silicone rubber being vulcanized after the formation of the layer of silicone rubber on the resin layer. A primer layer may be used between the heat-resistant resin layer and the silicone rubber layer.
