Abstract

PURPOSE: To facilitate production in spite of lamination type, omit complicated electrophotographic processes, and obtain clear picture image, by using specific charge carrier generating pigment, electron donor, and electron acceptor.
CONSTITUTION: A charge carrier generating pigment as shown in formula I [where, A is formula II, III, etc.; X is (substituted) aromatic ring such as benzene ring and naphthalene ring, indol ring, carbazol ring, and (substituted) hetero ring such as benzofuran ring; Ar1 is (substituted) aromatic ring, (substituted) hetero ring such as dibenzofuran ring; Ar2 is (substituted) aromatic ring; R1 is H, lower alkyl, (substituted) phenyl; R2 is lower alkyl, carboxyl, ester thereof], a layer containing an electron donor having a constitutional formula as shown in formula IV, and a layer containing an electron acceptor as shown in formula V are successively laminated on a conductive supporting body. This photoreceptor is suited to repeated use, and has a high sensitivity.
