The Langmuir-Blodgett multilayers of a copolyimide incorporating both copper-phthalocyanine and carbazole as electron donors were fabricated into a dual-layer photoreceptor as the charge-generating layer( CGL). The photoconductive properties of this photoreceptor were studied by photoinduced discharge measurement and compared with a reference photoreceptor in which the charge-generating layer was a solvent-casting film of the copolyimide. It was found that the photoreceptor consisting the copolyimide LB multilayers have the advantages of high photosensitivity, low residual potential, and high photodischarge rate. It was explained on the basis of the stacked molecule packing and charge-transfer complexes formation in the LB multilayers.
