ABSTRACT The electrostatic information recording medium according to the present invention comprises an electrode layer and an electric charge retaining layer. By improving the laminating method of electric charge retaining layer or by improving the layer arrangement or by converting electrostatic information to the visible information or position information, high information retaining property can be obtained and the accumulated electrostatic information can be maintained for long period. In the electrostatic information recording method according to the present invention, an electrostatic information recording medium is placed face-to-face to a photosensitive member having photoconductive layer on an electrode. The image exposure is performed by applying voltage between two electrodes, and the electrostatic information corresponding to the image exposure is recorded on the electrostatic information recording medium. The electrostatic information recorded in the electric charge retaining layer is easily reproduced by reading surface potential and by amplifying and outputting, or by electro-optical reading method, and further, by toner development. - 158 - The electrostatic information recording medium according to the present invention has excellent memory capacity with information density of 8 x 108 bits/cm2. For example, it is possible to record the information by electrostatic information recording method using a photosensitive member, to record analog, digital, image, sound and (0.1) information, and to apply for electrostatic recording card and the like. - 159 -
