Claim:
1. A developer carrying member, comprising: an electroconductive substrate; an elastic layer on the substrate; and a surface layer covering a surface of the elastic layer, the surface layer containing a modified acrylic urethane resin synthesized from (i) a modified acrylic polyol containing an ester bond, (ii) an isocyanate and (iii) a polyol comprising a structure represented by formula (2), and at least one structure selected from the group consisting of formulae (3) and (4), and having a constituent unit represented by formula (1): in which R U represents a urethane resin having, between two adjacent urethane bonds, said structure represented by formula (2), and said at least one structure selected from the group consisting of formulae (3) and (4), and L represents a divalent linking group containing an ester bond (—O—C(═O)—) wherein 10.5≦(B)/(A)≦50 when (A) is a number of moles of a hydroxyl group in the modified acrylic polyol and (B) is a number of moles of hydroxyl groups in all polyols other than the modified acrylic polyol.
