Abstract
PURPOSE: To prepare an original printing plate not requiring wetting water, by forming a toner image by the electrophotographic method on a silicone resin-containing insulating layer provided on a support with a photoconductive layer between, and applying high voltage to the insulating layer covered with the above image.
CONSTITUTION: 5W100μ thick photoconductive layer 2 and 1W30μ thick insulating layer 1 containing a silicone resin (hardenable silicone resin, solvent soluble silicone rubber, or the like) are laminated on support 3 to form a photoreceptor. A static image is formed on layer 1 of the above photoreceptor by the electrophotographic method, and this is developed and fixed to form toner image 6, then high voltage (2W6kV) is applied to the layer 1 surface with roller electrode 7, and the surface not covered with image 6 is made affinitive to ink to form an original lithographic printing plate. In addition, layer 1 is attached to layer 2 using strippable adhesive layer 5, and after high voltage application layer 1 may be stripped and used for an original printing plate.
