ABSTRACT:
An electrographic apparatus comprising a photosensitive screen composed of an insulating layer, two electrically conductive layers coated on opposite sides of the insulating layer and a photosensitive layer coated on one of said electrically conductive layers, and a bias electric source connected between the two electrically conductive layers and producing, on a dielectric coated record sheet, an electrostatic latent image corresponding to an image to be reproduced is disclosed. The apparatus comprises means for adjusting a bias voltage supplied from the bias electric source and applied between the two electrically conductive layers.
