Patent ID: 8655238

Claim:
A developing member, comprising in the following order: a mandrel; an elastic layer; and a resin layer, wherein: the resin layer comprises a polyurethane resin obtained by reacting an isocyanate compound with a polyol compound; and the elastic layer comprises a cured product of an addition polymerization type silicone rubber composition comprising the following (a) to (d): (a) an organopolysiloxane having two or more alkenyl groups bonded to a silicon atom in one molecule and having a methyl group as a group other than the alkenyl groups bonded to the silicon atom; (b) an organopolysiloxane having three or more hydrogen atoms bonded to a silicon atom in one molecule and having a methyl group as a group bonded to the silicon atom; (c) carbon black; and (d) an organopolysiloxane represented by the following formula (1) and having a weight average molecular weight Mw of 18,000 or more and 110,000 or less and a molecular weight distribution Mw/Mn, where Mn represents a number average molecular weight, of 1.0 or more and 2.0 or less: in the formula (1), R 1 represents an alkenyl group having 2 or more and 4 or less carbon atoms, R 2 represents a functional group capable of reacting with an isocyanate group, and n represents an integer of 1 or more.
