ABSTRACT:
The present invention relates to electrophotography, and in particular to the formation of a permanent image in one or more colors from latent electrostatic images which correspond to the color separations of an original and the developing of which is effected by means of a developer composed of polymer particles containing at least one dyestuff which can sublime or vaporize at between 100.degree. and 250.degree. C. The recording is effected under dry conditions by vaporization or sublimation of the dyestuffs present in the developers, without any fixing operation following the transfer of the dyestuffs onto the support which receives the recording.
