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.
Claims16
A photoconductive screen, comprising:
- a conductive screen substrate with many perforations therein, said conductive screen substrate being a seamless and endless rotatable loop;
- an insulating layer formed substantially on one side of said screen substrate;
- the surface of said screen substrate on said one side thereof not having any adjacent surface portions defining an angle of 90.degree. or less therebetween;
- a biasing conductive layer substantially covering said insulated layer and formed substantially only on said one side of said screen substrate without contacting the opposite side of said screen substrate so as not to short-circuit to said screen substrate;
- and
- a photoconductive layer substantially covering said conductive layer;
- wherein an electrostatic image can be formed on said photoconductive screen so as to control a flow of charged particles for formation of an electrostatic latent image on a chargeable layer thereof.
