DEVELOPING MEMBER, MANUFACTURING PROCESS THEREFOR AND ELECTROPHOTOGRAPHIC IMAGE-FORMING APPARATUS

摘要

Provided is a developing member capable of suppressing occurrence of compression set. The developing member comprises a substrate; an elastic layer provided on the substrate; and a coating layer provided on the elastic layer, wherein the elastic layer contains a cured substance of a mixture containing the following (A) to (D): (A) organopolysiloxane having two or more vinyl groups bonded to a silicon atom in one molecule and having a viscosity at 25°C of 10 Pa·s or more and 100 Pa·s or less; (B) organopolysiloxane including constituent units of SiO 4/2 unit and R 1 R 2 R 3 SiO 1/2 unit, where R 1 , R 2 , and R 3 each represent one of a methyl group and a vinyl group, and having two or more vinyl groups bonded to a silicon atom in one molecule; (C) organohydrogenpolysiloxane having two or more hydrogen atoms bonded to a silicon atom in one molecule; and (D) carbon black.
