Patent ID: 8798508

Claim:
A developing member comprising an electroconductive substrate, an elastic layer formed on the substrate, and a surface layer which covers a surface of the elastic layer, wherein the surface layer comprises a first resin, a second resin, and an electronically conductive filler, the first resin has, between two adjacent urethane linkages, a structure represented by the following structural formula (1), and one or both of structures selected from a structure represented by the following structural formula (2) and a structure represented by the following structural formula (3), and the second resin has a structure represented by the following structural formula (4), and one or both of structures selected from a structure represented by the following structural formula (5) and a structure represented by the following structural formula (6): where R 1 represents a hydrogen atom or a methyl group, and R 2 represents a straight chain or branched alkyl group having 1 to 4 carbon atoms; where R 3 represents a hydrogen atom or a straight chain or branched alkyl group having 1 to 4 carbon atoms; and where R 4 represents a hydrogen atom or a methyl group, R 5 represents an alkylene group having 1 to 4 carbon atoms, and R 6 represents a hydrogen atom or a straight chain or branched alkyl group having 1 to 4 carbon atoms.
