(57) [Summary] (Correction) [Purpose] To obtain an electrophotographic photoreceptor having high sensitivity and excellent potential stability and durability during repeated use. [Structure] The following general formula (Ar 1 to Ar 6 are aromatic ring groups and heterocyclic groups, except for the case where all of them are phenyl groups or phenylene groups) are used as the charge-transporting substance of the electrophotographic photosensitive member: R 1 to R 4 Is an aromatic ring group, a heterocyclic group, a hydrogen atom, a halogen atom, a hydroxyl group, Amino group, C1-6 alkoxy group, C1-6 alkyl group. ) At least one triphenylamine derivative represented by |
