Filed: 1992-04-21
Abstract: PURPOSE: To provide a printing method, which includes the forming of a printed matter having an improved resolution by the use of a pyroelectric material, and to provide a device therefor. CONSTITUTION: The printed matter thermally exposes a pyroelectric image- forming member 12 in a polarization mode, and on the other hand, neutralizes a surface electric charge, and then, cooles the exposed surface of the image- forming member to generate an electrostatic latent image on the surface thereof.
