Abstract

A process and a device for the image-differentiated development (inking) of a latent electrostatic image on an image carrier is disclosed, wherein, in an unlimited wide area, a fluid inking agent is applied to the image areas of the image carrier in the form of ink jets. The image areas have a potential V.sub.B, which is sufficient, in addition to an offset potential V.sub.O of the nozzles, to produce ink jets, which image the image areas of the image carrier.
