Abstract
PURPOSE: To obtain plural sheets of copies from one time of electrostatic latent image formation by superposing a transparent insulation layer, material layer and charge detecting plate on a photosensitive plate, applying a DC electric field between the substrate and electrode and radiating light.
CONSTITUTION: A photosensitive plate 9 is constituted by a conductive substrate 1 and a photosensitive layer 2, and a charge detecting plate 10 is constituted by a transparent insulation layer 4, a material layer of transmittance changing with electric fields, e.g., field effect type liquid crystal 5 and a transparent electrode 6. Differences occur between the internal electric field of the liquid crystal parts 11 in proximity to the portions where there are surface charges 3 and the internal electric field in the liquid crystal parts 12 of the portions where there are no surface electric fields. When light 8 is radiated in this state from above the deecting plate 10, light is radiated only to the portions where there are the surface charges on the photosensitive plate 9. The carriers generated by this light are separated by the DC electric field applied by a DC power source 7 between the substrate 1 and electrode 6 and only the positive charges are induced in the photosensitive plate surface. Thereby, the latent images of weak intensity may be amplified and the sharp latent images may be obtained.
