Electrophotographic photoreceptor, process for producing the same, and use of said photoreceptor for forming an image

摘要

The invention enables the forming of a highly characteristic image using an electrophotographic photoreceptor the charge-generating layer of which can be produced with better coating properties and which is highly sensitive and electrostatically highly stable in repeated use. The charge-generating layer of a function-separated type photoreceptor contains a tau -type non-metallic phthalocyanine and a vinyl chloride-vinyl acetate copolymer. The weight ratio of tau -type non-metallic phthalocyanine to the vinyl chloride-vinyl acetate copolymer is preferably 1/3 to 3/1 by weight and the copolymer is suitably of vinyl chloride and vinyl acetate, vinyl chloride, vinyl acetate and maleic acid or vinyl chloride, vinyl acetate and vinyl alcohol, especially one containing at least 10% by weight of vinyl alcohol.
