ABSTRACT:
In an electrographic printing device, an image generating system generates an electrical charge image on an image carrier element. The electronic charge image is made visible by a developer station via charged ink particles, the image being subsequently transferred onto a final image medium and fixed thereon. A speed control is provided which: continuously varies speed of the image carrier element from zero up to a limit speed; adapts charge intensity of the image carrier element to its speed; adapts an exposure intensity for exposure according to the image and in a deletion exposure of the image carrier element to its speed; and keeps a supply of toner to the image carrier element constant per area.
