Disclosed is a photoreceptor for electrophotography comprising a carrier generation layer and a charge transport layer. The organic charge generating substance has, at the time of positive charging, a photosensitivity less than the photosensitivity at the time of negative charging.

Photoreceptor for positive electrostatic charge

A photoconductive screen includes a conductive screen substrate with many perforations therein, an insulating layer formed substantially on one side of the screen substrate, a biasing conductive layer substantially covering the insulating layer, and a photoconductive layer substantially covering the conductive layer. An image of electrostatic charges can be formed on the screen to control a flow of charged particles for formation of an electrostatic latent image in a chargeable layer under exposure to the flow of charged particles.
