ABSTRACT:
A photosensitive screen for an electrographic apparatus adapted to modulate a flow of corona ions by an electrostatic latent image produced thereon is disclosed. The photosensitive screen is composed of an electrically conductive mesh which is coated on one side with an insulating layer and an electrically conductive layer superimposed one upon the other in the order as mentioned and coated on the other side with a photosensitive layer.
The photosensitive screen comprises further an insulating thin film layer which covers at least the electrically conductive layer for the purpose of protecting it against surrounding atmosphere and hence improving durability thereof.
