ABSTRACT:
An electrographic process which makes use of a photosensitive screen is disclosed. The photosensitive screen is composed of an electrically conductive support, a photoconductive member coated on the electrically conductive support and a dot-, line- or mesh-shaped insulating member coated on the surface of the photoconductive member with an interface formed between the photoconductive member and the insulating member. An electric charge is trapped on the interface and an electrostatic latent image corresponding to a manuscript image is produced on the insulating member only, thereby obtaining an electrographic image having excellent resolving power.
