Abstract

PURPOSE: To make dampening water unnecessary by manufacturing a printing original plate using silicone resin.
CONSTITUTION: Printing drum 6 is formed by laminating photoconductive layer 2 composed mainly of various insulating resins and layer 1 containing silicone resin such as setting silicone resin or solvent-soluble silicone rubber on the surface of support 3. Drum 6 is subjected to primary charing, simultaneous secondary AC de- electrification and imagewise exposure, and uniform exposure to form an electrostatic latent image on the surface of layer 1. Toner 8 containing particles of a lipophilic resin such as polystyrene resin and having an affinity for ink is applied with roller 7 to form toner image 9, which is then transferred onto transfer paper 11 through blanket drum 10.
