Abstract
Disclosed is a laminated photosensitive material for the electrophotography, which comprises an electroconductive substrate, a charge-generating layer composed of a vacuum deposition film of metal-free phthalocyanine formed on the substrate and a charge-transporting layer formed on the charge-generating layer, wherein the metal-free phthalocyanine film is a metal-free phthalocyanine particle layer composed mainly of .alpha.-type fine crystals having a crystal particle size of 100 to 2000 .ANG. and the vacuum deposition film has a thickness of 500 to 3000 .ANG. and a dark electroconductivity lower than 10.sup.-10 (.OMEGA.-cm).sup.-1. In this laminated photosensitive material, the initial charge quantity is improved, and the electrophotographic characteristics are stabilized when the photosensitive materials is used repeatedly or continuously.
