Abstract
A process of producing a cleaning blade including a silicon rubber base and a resin layer which acts as a lubricant on the surface of the rubber is produced by molding a rubber material having resin powder dispersed therein at a temperature less than the softening or melting point of the resin, cutting an end of the rubber, and vulcanizing the molded rubber at a temperature higher than the softening or melting point of the resin. The resin layer is selected from polypropylene, polyvinylidene fluoride, polyethylene, or polyester.
