Abstract

A carrier or substrate for a photoconductor to be used for the formation of an electrophotographic recording element, particularly an imaging drum for an electrophotographic printing press, wherein the carrier is made of a metal or a metal alloy, preferably of aluminum, is prepared wherein the surface of the carrier supporting the photoconductor, used to form a barrier layer, is oxidized, preferably by etching and/or anodizing. The oxidized surface of the barrier layer is sealed with a sealing material following oxidation, and a preservative or impregnating agent is used as the sealing material.
