2. Description of the Related Art As an aromatic polycarbonate resin,
A polycarbonate resin obtained by reacting 2,2-bis (4-hydroxyphenyl) propane (hereinafter abbreviated as bisphenol A) with phosgene or diphenyl carbonate is known as a typical one. Such polycarbonate resin from bisphenol A has excellent properties in terms of transparency, heat resistance, dimensional accuracy and mechanical strength, and is therefore used in many fields. As one example thereof, various studies have been made as a binder resin for an organic photoconductor used in electrophotography. As a typical configuration example of the organic photoreceptor,
Examples thereof include a laminated-type photoreceptor in which a charge generation layer and a charge transport layer are sequentially laminated on a conductive substrate. The charge transport layer is formed of a low molecular charge transport material and a binder resin, and many aromatic polycarbonate resins have been proposed as the binder resin. However, the inclusion of a low-molecular weight charge transport material reduces the mechanical strength originally possessed by the binder resin, which causes deterioration of wear of the photoreceptor, scratches, cracks, etc., and impairs the durability of the photoreceptor. Has become.
