PHOTORECEPTOR FOR ELECTROPHOTOGRAPHY, PROCESS FOR PRODUCING THE SAME, AND ELECTROPHOTOGRAPHIC APPARATUS

WIPO Patent Application WO/2010/092695

A1

Provided is a photoreceptor for electrophotography in which the photoreceptor drum surface can have reduced frictional resistance throughout the period from the beginning to after printing. The photoreceptor is reduced in wear and can give satisfactory images. Also provided are a process for producing the photoreceptor and an electrophotographic apparatus. The photoreceptor for electrophotography has a photosensitive layer containing, as a resin binder, a copolyarylate resin comprising structural units represented by the following chemical structural formula (1). (In the chemical structural formula (1), partial structural formulae (A), (B), (C), (D), (E), and (F) represent structural units constituting the resin binder. Symbols a, b, c, d, e, and f indicate the amounts in mol% of structural units (A), (B), (C), (D), (E), and (F), respectively, provided that a+b+c+d+e+f is 100 mol%. R1 to R19 each represents hydrogen or the like, and s and t each is an integer of 1 or larger.)
