Abstract

Procedure for making copies of a graphic original, characterized in that a photoconductive layer is loaded in the dark and then it is exposed as an image to form on it a latent charge image corresponding to the image of the original, the image of latent filler with a thermoplastic toner powder in which the thermoplastic constituent consists of at least 50% by weight of a copolymer of styrene with indene or an alcoholicindene, the copolymer of which contains at least 50% by weight of styrene and which may also contain acrylonitrile units, and the powder image is fixed, optionally after it has been transferred to a receiving surface, to produce a permanent copy.
