A conveying belt has a cylindrical base layer, and a surface layer that is formed on the outer peripheral surface of the base layer. The base layer contains polyimide or polyamide-imide, and has an elastic modulus from 3-7 GPa, inclusive. The surface layer is configured as a cured object from a resin composition that contains a fluororesin having a hydroxy group, an isocyanate curing agent, and a silicone copolymer. The silicone copolymer is a copolymer containing a silicone unit and another kind of unit not having a siloxane skeleton, has a hydroxy group, and contains siloxane units in a proportion of at least 95 mol % and less than 100 mol %, or from 40-70 mol %, inclusive. The silicone copolymer content in the resin composition is 1-5 parts by mass, inclusive, relative to a total 100 parts by mass of the fluororesin and the isocyanate curing agent.

An electrophotographic device member R is used in an electrophotographic device. The electrophotographic device member R has a surface layer. The surface layerhas a matrix polymerforming a skeleton of the surface layerand a surface modifiercontained in the matrix polymer. The surface modifieris composed of a copolymer containing, in its molecule, a first polymerization unit derived from a (meth)acrylate having a silicone groupand a second polymerization unit derived from a (meth)acrylate having a fluorine-containing group
