ABSTRACT:
The present invention relates to a lithographic printing plate which can eliminate disadvantages of conventional zinc oxide master papers and has sensitivity sufficient for practical use in respect of long wavelength laser light. The invention contemplates to provide the lithographic printing plate which is fabricated by charging an electrophotographic plate involving a photoconductive layer on a conductive substrate, the photoconductive layer being prepared by dispersing a mixture containing 50 wt % or less of a phthalocyanine pigment/(zinc oxide and zinc sulfide) into a binder resin, exposing the electrophotographic plate to an image to form the electrostatic latent image, developing the exposed electrophotographic plate by the use of an ink receptive toner, and fixing the plate thus developed.
