Patent ID: 7123867

Claim:
In an electrophotographic printing device, having a developer unit and a photoconductor, wherein the photoconductor is connected directly or with interposition of at least one transfer medium with a substrate to be imprinted, located in a transfer zone, wherein a charger is assigned to the substrate, and wherein the substrate can be conveyed through the transfer zone by a conveying device, the improvement comprising: the charger arranged on a side facing a surface of the substrate ( 30 ) to be imprinted and directly acting on the surface to be imprinted and wherein the charger is a primary charger arranged upstream of the transfer zone in a conveying direction and a secondary charger downstream of the transfer zone, and the primary charger and the secondary charger act on the surface of the substrate ( 30 ) to be imprinted and wherein the primary charger and the secondary charger are of the same polarity, and wherein a distance of the primary charger ( 16 ) from the secondary charger ( 18 ) is less in the conveying direction than the extension in the conveying direction of the surface of the substrate ( 30 ) to be imprinted, and the substrate is one of glass, plastic, ceramic, or ceramic-glass.
