ELECTROPHOTOGRAPHIC DEVICE MEMBER

摘要

An electrophotographic device member can be configured as a roll member 1, a blade member 2, a belt member 3 or the like, and a modified rubber elastic body 12 is used as a material for a portion including the surfaces of the respective members. The modified rubber elastic body 12 has a rubber elastic body 121 having rubber elasticity and a surface-treated layer 122 composed of a cured product of photocurable composition impregnated into the rubber elastic body 121 from the surface thereof. The photocurable composition is configured to include a (meth)acryl monomer, a photopolymerizable polymer having a silicone group and/or a fluorine-containing group and a (meth)acryloyl group in a molecule, and a photopolymerization initiator.
