Abstract

An image forming apparatus has a first image bearing member and an intermediate transfer member onto which a toner image formed on the first image bearing member is primarily transferred and through which the toner image thus transferred is secondarily transferred onto a second image bearing member. The intermediate transfer member has a surface layer on a base layer and the surface layer contains a polyurethane resin obtained by the reaction of an olefinpolyol with an isocyanate.
