Patent ID: 8785090

Claim:
An electrophotographic photoreceptor comprising: a conductive substrate; and a single-layer photosensitive layer that is provided on the conductive substrate and includes a binder resin, at least one kind of charge generation material selected from hydroxygallium phthalocyanine pigments and chlorogallium phthalocyanine pigments, a hole transport material represented by Formula (1), and an electron transport material represented by Formula (2): wherein in Formula (1), R 1 , R 2 , R 3 , R 4 , R 5 , and R 6 each independently represent a hydrogen atom, a lower alkyl group, an alkoxy group, a phenoxy group, a halogen atom, or a phenyl group which may have a substituent selected from a lower alkyl group, an alkoxy group, and a halogen atom; and m and n each independently represent 0 or 1: wherein in Formula (2), R 11 , R 12 , R 13 , R 14 , R 15 , R 16 , and R 17 each independently represent a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, or an aryl group; and R 18 represents a linear alkyl group having from 5 to 10 carbon atoms.
