Electrophotographic photoreceptor, process cartridge, and image forming apparatus

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), R1, R2, R3, R4, R5, and R6 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), R11, R12, R13, R14, R15, R16, and R17 each independently represent a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, or an aryl group;
• and R18 represents a linear alkyl group having from 5 to 10 carbon atoms.
