ABSTRACT:
Disclosed is a process for preparing a planographic printing plate by electrophotographic or electrographic means by producing a charge image on a photoconductive or highly insulating layer, developing the image onto the free surface of a dielectric intermediate carrier in contact with the photoconductor or highly insulating layer by means of a developer, which comprises dispersed thermoplastic particles having a melting range from about 90.degree. to 130.degree. C., and transferring and fixing the toner image to the planographic printing plate at a temperature within the melting range of the thermoplastic particles after the intermediate carrier has been separated from the charge image.
