Dry planographic printing plate and printing method employing the same

Abstract From the Canadian patent

This invention provides a dry planographic printing plate prepared by forming on an electrically conductive support a photoconductive layer composed of a binder and photoconductive powder dispersed in the binder charging and the, image-exposing a resultant photosensitive plate and finally, developing by means of a conductive toner and fixing the conductive toner. This invention also provides a dry planographing printing method including reversal-developing said printing plate by using a toner, transferring the toner to a sheet of transfer material, and then fixing the toner as, well as an apparatus used in said printing method.
