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 R 1  to R 8  each 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).

Claim (Index 1):
An electrophotographic photoreceptor comprising:\n 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 R 1  to R 8  each 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; and R 1  and R 2 , R 2  and R 3 , R 3  and R 4 , R 5  and R 6 , R 6  and R 7 , and R 7  and R 8  are optionally individually bonded to each other to form aromatic rings), wherein\n an amount of the silane coupling agent is approximately from 5 parts by mass to 15 parts by mass relative to 1 part by mass of the compound represented by General Formula (ID).
