ELECTROPHOTOGRAPHIC FIXING MEMBER, FIXING APPARATUS AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS

摘要

An elastic layer of the fixing member contains a silicone rubber, an inorganic filler and vapor grown carbon fibers, relationships of 3X+30Y≦170, 25≦X≦50 and 0.5≦Y≦3.1 are satisfied when a volume percent of the inorganic filler compounded in the elastic layer is expressed by X (%) and a volume percent of the vapor grown carbon fibers compounded in the elastic layer is expressed by Y (%), and a ratio of a fiber length to a fiber diameter of the vapor grown carbon fibers, aspect ratio, is 50 or more.
