An electrophotographic photoreceptor comprising an electrically conductive substrate and a photosensitive layer formed thereon, wherein said photosensitive layer contains an arylamine compound of the following formula (I):
 wherein X is a hydrogen atom or a group of the formula (II):
 Y is a group of the formula (III) or (IV):
        -O-A¹-O-   (III)
        -A²-O-A³-   (III)
wherein A¹ in the formula (III) is a bivalent hydrocarbon residue which may have substituents, and each of A² and A³ in the formula (IV) is an alkylene group which may have substituents, an arylene group which may have substituents, or a group wherein an alkylene group which may have substituents and an arylene group which may have substituents, are bonded, and A² and A³ may be the same or different from each other; each of Ar¹ and Ar² which may be the same or different, is an alkyl group which may have substituents, an aryl group which may have substituents, or a heterocyclic group which may have substituents; each of R¹, R², R³ and R⁴ which may be the same or different, is a hydrogen atom, a halogen atom, an alkyl group which may have substituents, an alkoxy group which may have substituents, or a substituted amino group; each of R⁵, R⁶, R⁷, R⁸, R⁹ and R¹⁰ which may be the same or different, is a hydrogen atom, an alkyl group which may have substituents, an aryl group which may have substituents, or a heterocyclic group which may have substituents, or R⁶ and R⁷, or R⁹ and R¹⁰ are condensed to form a carbon ring group which may have substituents, or a heterocyclic group which may have substituents, provided that with respect to the pair of R⁶ and R⁷ and the pair of R⁹ and R¹⁰, when one of each pair is a hydrogen atom or an alkyl group, the other is an aryl group or a heterocyclic group.
