Abstract

Provided is a member for electrophotography, where an elastic layer including a silicone rubber and a release layer including a fluorine resin are bonded sufficiently without any adhesive layer interposed therebetween. The member for electrophotography includes a substrate; an elastic layer including a silicone rubber, on the substrate; and a release layer provided in direct contact with the surface of the elastic layer, where the release layer includes a fluorine resin selected from the group consisting of PFA, FEP, PTFE, ETFE, PCTFE, ECTFE, and PVDF, and the elastic layer undergoes a cohesive failure when the release layer is peeled from the elastic layer in accordance with 'Determination of peel strength of bonded assemblies. Part 1: 90 degree peel' specified by the Japanese Industrial Standards (JIS) K 6854-1:1999.
