  • Electrostatic information recording medium and electrostatic information recording and reproducing method
    Patent number: 5718996
    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.
    Type: Grant
    Filed: August 27, 1996
    Date of Patent: February 17, 1998
    Assignee: Dai Nippon Printing Co., Ltd.
