Abstract of the Disclosure The invention deals with a procedure for making a repeatedly reusable photoconducting charge image carrier, characterized in that a first coat containing at least one insulating nonvolatile ingredient is applied to a substrate, in order to produce an insulating layer on the substrate after the coat dries, following which a second coat, containing photoconducting material and at least one binder for it, is applied to this insulating layer, at least one sensitizer for the photoconducting material being mixed into the second coat and the photographic material being dispersed in a solution of at least one binder, the solvent for the second coat being one which will not dissolve the insulating layer, whereupon the substrate, covered by an insulating layer and a second coating, is again dried, and if it was not conducting from the offset, the substrate is made conducting at the latest after the second coat is dried, the resulting charge image carrier finally being conditioned, to obtain a charge image carrier usable for at least about 4000 cycles.
