Electrophotographic photoreceptor, process cartridge, and image forming apparatus

Abstract

An electrophotographic photoreceptor includes a conductive substrate; an undercoat layer formed on the conductive substrate and containing a polyurethane resin, metal oxide particles, a silane coupling agent, and a compound represented by General Formula (ID); and a photosensitive layer formed on the undercoat layer (where Rto Reach independently represent a hydrogen atom, a nitro group, a cyano group, a halogen atom, a hydroxyl group, a saturated or unsaturated aliphatic hydrocarbon group optionally having a substituent, an aromatic hydrocarbon group optionally having a substituent, an alkoxy group optionally having a substituent, an aryloxy group optionally having a substituent, a sulfo group optionally having a substituent, an amino group, an alkylamino group optionally having a substituent, or an arylamino group optionally having a substituent).
