Patent ID: 10125236

Abstract:
To provide an elastic roll for an electro-photographic apparatus that includes an elastic body layer having a low hardness and being excellent in fatigue resistance, and thus is resistant to fatigue, and to provide a method for manufacturing the same.An elastic roll 10 for an electrophotographic apparatus includes a shaft body 12, and a foamed elastic body layer 14 provided on an outer periphery of the shaft body 12, wherein the foamed elastic body layer 14 consists of a silicone rubber foamed body including a plurality of air bubbles 18 in its base material containing cross-linked silicone rubber and a reinforcement material, and wherein the foamed elastic body layer has a communication degree of 40% or more. It is preferable that the elastic roll 10 should further include a skin layer 14a in the foamed elastic body layer 14 on an outer peripheral side.
