Electrophotographic photoreceptor

Abstract

Abstract PURPOSE:To provide high sensitivity and durability by using polyphenylene oxide having such a low average degree of polymn. as 10-100 as a resin binder in an electric charge transferring layer so as to make the binder soluble in an easily handleable solvent such as toluene. CONSTITUTION:Polyphenylene oxide having 10-100 degree of polymn. and synthesized from specified substd. phenol by a know oxidation polycondensation method under reaction conditions which ensure a low degree of polymn. is used as a resin binder in the electric charge transferring layer of a laminated sensitive body. A substd. phenol compd. having alkyl groups such as methyl or ethyl group at the 2- and 6-positions is especially used as the starting material. A low-cost and relatively easily handleable solvent which hardly affects the human body, e.g., xylene, toluene or O-xylene can be used and a sensitive body satisfying requirements such as wear resistance, dimensional stability, weather resistance, charge retentivity and low residual potential important to a sensitive body for copying is obtd.
