摘　　要：The configuration and photoelectron processes of nletal-free phthalocyanine multi-layered film have been discussed in detail. And by the study of photodecay surface residual potential, the results obtained are that the initial surface dark potential (Vo) charged from DC corona voltage (-6kV) is 910V, the dark surfacc potential (Vd) measured atter 2-sec. dark decay is 825V, it is 90.3% of the initial surface dark potential (Vo), the rate of dark decay (DR) calculated from initial surface potential (Vo) and dark surfacc potential (Vd) is 9.3%, the surface residual potential (Vr) measured after 1.5-sec. illumination is 40V, the light sensitivity (E1/2) calculated frorn illumtinating power (EL) and the time of half photo-decay (t1/2 ) is 2 lux.sec. These values are iu valid values region of laser printers. Indicating that metal-free phthalocyanine used in function separated multi-layered film is an appropriate photogenerator-photoconductor. It would pave a solid road to small-size for copies, especially for laser printers, and much expanded scope of studies and applications in organic photoconductor.The configuration and photoelectron processes of nletal-free phthalocyanine multi-layered film have been discussed in detail.
