A novel method for preparing an electrophotographic photoreceptor is disclosed, which comprises laminating a charge generating layer and a charge transporting layer in this order on an electrically conductive substrate via an undercoating layer, wherein the coating solution for said undercoating layer contains an alkoxide coupling agent represented by formula (I), an aliphatic alcohol solvent containing at least the same number of carbon atoms as in the alkoxy group in said alkoxide coupling agent, and at least one compound selected from the group consisting of aromatic solvents, ethylene glycols and propylene glycols: Xm-m-(OR1)N (I) wherein R1 represents an alkyl group having 1 to 5 carbon atoms; M represents Si, Ti, Zr or Al; X represents an organic group; m represents an integer of 0, 1 or 2; and n represents an integer of 1 to 4, provided that when M is Si, Ti or Zr, n is an integer of 1 to 4 and m is an integer of (4-n) and when M is Al, n is an integer of 1 to 3 and m is an integer of (3-n).
