ABSTRACT:
An electrophotographic process comprising uniformly charging a composite photosensitive body with a charging polarity exhibiting a response property to a visible light, said composite photosensitive body being composed of a photoconductive semiconductor for producing carrier when illuminated by the visible light and a light transmitting organic photosemiconductor superimposed one upon the other, illuminating the charged composite photosensitive body with a light image by the visible light and producing thereon a first electrostatic latent image and producing thereon a second electrostatic latent image based on said first electrostatic latent image, said second electrostatic latent image having a polarity which is opposite to said charging polarity.
