PRINTING PRESS USING CHARGE RETAINING MEDIUM, ITS MANUFACTURING METHOD AND STRIPPING SYSTEM USING CHARGE RETAINING MEDIUM.

摘要

The printing press has a photoconductive layer of a photosensitive member and a charge retaining layer of a charge retain medium facing each other with a predetermined distance. After a power source is connected, light of a predetermined wavelength is irradiated to the photosensitive member to form an electrostatic latent image in the charge retaining layer of the charge retaining medium. Next, the charge retaining medium is disconnected from the power source toner is applied onto the charge retaining layer and development and fixing are carried out. Etching is then conducted using the resulting toner image as a mask to remove the portions of the charge retaining layer to which the toner is not deposited. In this manner a printing plate having a scanned portion formed by the toner and the charge retaining layer on the conductive substrate can be obtained. According to this plate, the toner image is formed directly on the charge retaining layer of the charge retaining medium.
