Electrophotographic photoreceptor belt

Abstract

An electrophotographic photoreceptor which is excellent in wear resistance and crack resistance and has a long photoreceptor lifetime can be produced by using a polycarbonate resin composition prepared by blending 100 parts by weight of a polycarbonate resin with 0.01 to 5 parts by weight of a silicone-modified polyurethane obtained by reacting (a) a diol component represented by the general formula (I) with (b) an active hydrogen containing polysiloxane compound, (c) a polyisocyanate component and, if necessary, (d) a chain extender as the material for the backing film of a photoreceptor belt. [Chemical formula 1](I) wherein R1 and R2 are each independently hydrogen or alkyl; R3 is hydrogen, alkyl, alkoxy, halogeno or alkoxycarbonyl; M is a single bond, substituted or unsubstituted alkylene, or oxyalkylene; and n is an integer of 0 to 4.
