Patent ID: 8703370

Claim:
An electrophotographic photoreceptor, comprising: a conductive substrate; and a photosensitive layer provided on the conductive substrate and containing a resin binder that is a polycarbonate resin having structural units represented by General Formulae (1) and (2) below: where, in General Formula (1), X is General Formula (3) or (4) below, and the polycarbonate resin may contain, as structural units represented by General Formula (1), both units in which X is General Formula (3) below and units in which X is General Formula (4) below: where t and s in General Formulae (3) and (4) are each an integer of 1 or greater; where, in General Formula (2), R 1 and R 2 may be the same or different, and are hydrogen atoms, C 1-12 alkyl groups, halogen atoms, C 6-12 optionally substituted aryl groups or C 1-12 alkoxy groups, c is an integer from 0 to 4, and Y is a single bond, —O—, —S—, —SO—, —CO—, —SO 2 —, or —CR 3 R 4 — (in which R 3 and R 4 may be the same or different, and are hydrogen atoms, c 1-12 alkyl groups, halogenated alkyl groups or C 6-12 optionally substituted aryl groups), or C 5-12 optionally substituted cycloalkylidene group, C 2-12 optionally substituted α,ω-alkylene group, -9,9-fluorenylidene group, C 6-12 optionally substituted arylene group, a bivalent group including C 6-12 aryl group or arylene group; and a and b are the respective molar percentages of structural units (1) and (2) relative to the total number of moles of structural units (1) and (2).
