Abstract
An electrostatic information recording medium according to this invention includes an inorganic oxide layer 3 and a photoconductive layer comprising a charge-generating layer 4 and a charge-transport layer 5 laminated onto an electrode 2 in this sequence, as illustrated in FIG. 1. To record information, the information is exposed to light while voltage is being applied between the electrode 3 and another opposite electrode, or alternatively voltage is applied therebetween while the information is being exposed to light. After information recording, the electrostatic information recording medium is uniformly electrified on its surface as by corona charging, whereby the information can be easily reproduced in the form of electrostatic information. This recording medium, if tone-developed, can be used as an original plate for electrostatic printing.
