Electrophotographic photoreceptor, process cartridge, and image forming apparatus

An electrophotographic photoreceptor, comprising:

• a conductive base;
• and
• a photosensitive layer,
• the photosensitive layer including a charge generating layer and a charge transporting layer,
• the charge transporting layer including a hole transporting agent, a binder resin, and a phthalocyanine pigment,
• the binder resin including a polyarylate resin,
• the polyarylate resin including a repeating unit represented by the following general formula (1), a repeating unit represented by the following chemical formula (2), and a repeating unit represented by the following chemical formula (3),
• a ratio n1/n2 of the number n1 of repeating units represented by the general formula (1) to the number n2 of repeating unit represented by the chemical formula (2) being 1.0 or more,
• the hole transporting agent including a compound represented by the following general formula (10):
• in the general formula (1),
• R1 and R2 each independently represent a hydrogen atom or a methyl group, R3 represents a methyl group, and R4 represents a hydrogen atom or an alkyl group having 2 or 3 carbon atoms, or
• R1 and R2 each independently represent a methyl group, and R3 and R4 are bonded to each other to represent a cycloalkylidene group having 5 or 6 carbon atoms;
• in the general formula (10),
• R11 to R15 each independently represent an alkyl group having 1 to 8 carbon atoms or an alkoxy group having 1 to 8 carbon atoms, and a1, a2, a3, a4, and a5 each independently represent an integer of 0 or more and 5 or less.
