摘要： The present invention relates to a xeroprinting process, in particular a xeroprinting process comprising the following steps:(a) image-wise exposing to actinic radiation an electrostatic master having a photopolymerizable conductive layer to selectively polymerize and thereby increase resistivity in exposed areas of the layer;(b) forming a latent image of electrostatic charge by charging the master by corona discharge;(c) reversal developing the latent electrostatic image by depositing toner particles in the non-exposed areas of the layer;(d) transferring the toner image to another substrate and subsequent fusing;(e) resetting the process by cleaning and discharging the electrostatic master.According to a preferred embodiment the reversal development is effected by means of a development electrode inducing charges in the photopolymer plate opposite to the initial electrostatic image, and by means of dry electrophotographic toner.
