PURPOSE:To enable formation of the latent image of an original on a photosensitive body surface without using an optical system by enabling formation of the electrostatic latent image of the original image on one surface of porous paper contg. internally air. CONSTITUTION:The photoconductor layer surface 5-a of a drumshaped electrode 5 is uniformly electrified by an electrifier 7 and an original covered by a transparent insulating sheet 3 is sandwiched between an electrode plate 6 and a drum- shaped electrode 5. Such original is fed leftward by the rotation of the electrode 5 and an AC voltage is impressed between the electrodes 5-b and 6-b generate corona discharge in the paper layer of the original 1. The light generated in this stage transmits the sheet 3 while the light is attenuated by the image of the original surface 1-a. Said light arrives at the layer 5-a on the electrode 5. The layer 5-a is made conductive in accordance with the exposure and the electric charge electrified on the surface is destaticized through an inpedance circuit 11, by which the electrostatic latent image of the original image is formed on the surface of the layer 5-a. |
