Abstract:
Provided is an electrophotographic member, which hardly changes in performance even when being left to stand for a long time period. The electrophotographic member comprises a support, an elastic layer formed on the support, and a surface layer covering a surface of the elastic layer and containing a urethane resin, and in which the urethane resin comprises a reaction product of: a hydroxyl group-terminated prepolymer obtained by reacting a polyester polyol with a polyisocyanate; and an isocyanate-terminated prepolymer obtained by reacting a polyester polyol with a polyisocyanate.
