A multilayered electrophotographic photoreceptor comprising at least a charge generation layer containing a charge generation material and a charge transport layer containing a charge transport material in this order, on a conductive support, wherein the charge transport layer contains, as the charge transport material, an amine type compound represented by the following formula (I): wherein R1 to R9, which may be the same or different, respectively represent a hydrogen atom; a halogen atom; or an alkyl, cycloalkyl, alkenyl or alkoxy group which may have a substituent, provided that either one of R2 and R3 represents -N(Ar1)(Ar2); and Ar1 to Ar4, which may be the same or different, respectively represent an aromatic hydrocarbon residue or an aromatic heterocyclic residue which may have a substituent, and Ar1 and Ar2, or Ar3 and Ar4 may be combined with each other to form a condensed ring; and has photosensitive properties in coherent light of wavelength range from 400 to 450 nm.
