The present electrostatic information recording medium has an information density as expressed in terms of a high recording capacity of the order of 8.times.10.sup.8 bits/cm.sup.2, and makes it possible to process information in a planar state so that analog or digital information such as characters, line pictures, images, (0.multidot.1) information and sounds can be accumulated in the form of electrostatic charges. With the present electrostatic information recording medium, it is possible to obtain information of high quality and resolving power because of the information being accumulatable in electrostatic charge units. Due to its high charge retainability, it is further possible to store information permanently. Still further, it is possible to make inexpensive and simple recording/reproducing systems, since information can be output by reading local potentials of electrostatic latent images at any time and any scanning density.

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. The electrostatic information recording medium according to the present invention has excellent memory capacity with information density of 8.times.10.sup.8 bits/cm.sup.2. 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.
