　 Abstract:
　       Electrophotographic characteristics of negatively charged dual-layered photoreceptors,containing bisazo pigment [2,7-bis(1-azo-2'-hydroxy-3'-naphtho-2”-chloroanilide)fluoren-9-one] or its blended composites with vanadyl phthalocyanine(VOPc) as charge generation materials,and 4-(diethylmino)benzaldehyde-1,1-diphenylhydrazone as charge tranport material,have been studied.UV/Vis solid-state absorption spectra show that absorption spectra of the azo pigment can be broadened by blending with VOPc.The X-ray diffraction patterns of  the blended composites are also studied.
