Electrostatic charge image recording and reproducing method

Abstract

Abstract PURPOSE:To make the recording and reproducing system simple and low in the cost by using a photosensitive body so as to record a picture as an electrostatic latent image optically and analogically and reading and outputting a local potential of the electrostatic latent image with a scanning density at an optional point of time. CONSTITUTION:When a voltage is applied to electrode 7, 13 from a power supply 17, no change is caused between the electrodes since a photoconductive layer 9 is a high resistance at a dark place. However, when light is made incident from the photosensitive body 1, the part of the photoconductive layer 9 in which a light is made incident shows conductivity, discharge is caused with an insulation layer 11 and an electronic charge is stored in the insulation layer 11. A charge storage medium 3 is taken out to form an electrostatic latent image. A potential signal at an optical point on the storage medium 3 is collected as a data from the electrostatic latent image by using X, Y stages or the like by means of the electrostatic potential measuring means such as electron beam type or CT scanning type, the data is displayed while being picture processing.
