Abstract:
A method of electrophotographic copying of information utilizing the recording of an electrostatic image of the original information onto a recording photoreceptor, wherein said electrostatic image is in the form of a pattern that has spaced-apart charged regions of a certain polarity that correspond to image elements and are spaced by blanked uncharged regions, the method including at least one cycle comprising the steps:(a) forming a latent electrostatic image of the original information which is to be copied on an intermediate information carrier by means of an interaction between said recording photoreceptor and said intermediate information carrier, wherein the intermediate information carrier is a photoreceptor having an electrically conductive substrate carrying a photosemiconductor layer with a dielectric coating made of a high-resistance material that possesses desired mechanical properties, the intermediate information carrier being such that it, whilst being charged, stores the charge configuration corresponding to the original information during a desired period of time required for producing a desired number of copies of the original information;(b) developing said latent electrostatic image on the intermediate information carrier;(c) transferring the developed image from the intermediate information carrier onto a final information carrier; and(d) fixing the transferred image on the final information carrier.
