Abstract
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.
