Claim:
1. A member for electrophotography, comprising: a substrate; an elastic layer comprising a silicone rubber, provided on the substrate; and a release layer comprising a fluorine resin, provided in direct contact with a surface of the elastic layer, wherein the release layer comprises at least one fluorine resin selected from the group consisting of a tetrafluoroethylene-perfluoro(alkylvinylether) copolymer (PFA), a tetrafluoroethylene-hexafluoropropylene copolymer (FEP), polytetrafluoroethylene (PTFE), an ethylene-tetrafluoroethylene copolymer (ETFE), polychlorotrifluoroethylene (PCTFE), an ethylene-chlorotrifluoroethylene copolymer (ECTFE), and polyvinylidene fluoride (PVDF), wherein 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 Japanese Industrial Standards (JIS) K 6854-1:1999, and wherein a peak that indicates a bonding state of a fluorine atom is shifted toward a lower energy than a peak of a binding energy of a —CF
