Abstract
Electric discharge between a photosensitive member and a charge retaining medium is ON/OFF controlled by changing the gas pressure between these two members, so that it is possible to effect image recording in a state where a DC voltage is applied. Accordingly, it is possible to effect image recording on the charge retaining medium without the need for precise control for obtaining a high-voltage pulse and without employing an optical shutter. In addition, an electric charge that is emitted by a field is attracted to the charge retaining medium and accumulated on the surface thereof, thereby forming an electrostatic latent image, and thus making it possible to attain image recording of extremely high resolution.
