PURPOSE:To activate high picture quality and to visualize an electrostatic latent image reduced in the abrasion or deterioration of an electrostatic latent image forming medium by generating a powdery phenomenon on the electrostatic latent image forming medium to visualize the electrostatic latent image. CONSTITUTION:A belt-like latent image carrier 3 is wound around a pair of driving rollers 2a, 2b in an armor case having an opening on its front surface and a liquid crystal cell 4 is arranged on the front surface so as to be slightly separated from a non-display device to form a display part A. A pair of pressing rollers 7a, 7b are arranged on the reverse side against the liquid crystal cell 4 arranged on positions 9 close to the upper and lower ends of the latent image carrier 3 opposed to the liquid crystal cell 4. The pressing rollers 7a, 7b are released, a latent image carrying surface on which a positive electrostatic latent image is formed is carried to the display part A and then the pressing rollers 7a, 7b are adhered again to the liquid crystal cell 4. Consequently, the latent image is visualized on the surface of the liquid crystal surface. |
