Abstract

See full text

In a method to adjust hue of a print images by toner layer thickness a photoconductor element is charged to a charge potential. A potential image of the print image made up of image points is generated via exposure and discharge of the photoconductor element. The potential image is inked by charged toner via a developer element at a BIAS potential. With a character generator, generating a potential of an individual image point of the print image via local discharge of the photoconductor element, the potential of the image point lying between the BIAS potential and a potential established by a maximum achievable discharge depth of the photoconductor element, and so that the individual image points have same or different potentials, depending on the exposure, so that the exposed area overall has a resulting potential, and a depositing of toner on this area and therefore the toner layer thickness on this area is proportional to the resulting potential.
