Claim:
1. A transfer member for electrophotography comprising a surface layer having a surface for carrying toner, the surface layer containing a graft type copolymer comprising a polymer having a structure represented by formula (1) as a main chain, and a group containing a structure represented by formula (2) bonded to the main chain as a side chain and a group containing a structure represented by formula (3) bonded to the main chain as a side chain; and the surface of the surface layer has a matrix phase formed by a group containing a structure represented by formula (2), and a domain phase formed by a group containing a structure represented by formula (3), wherein in the copolymer the mass ratio of the group containing the structure represented by formula (2) to the main chain is 5 to 40 mass %, and the mass ratio of the group containing the structure represented by formula (3) to the main chain is 10 to 25 mass %: wherein R wherein R wherein X represents a fluorine atom or trifluorocarbon; p and q each independently represent an integer of 0 or more; and “p+q” represents an integer of 2 or more.
