Apparatus and method for development of potential images, produced on an intermediate image carrier, for an electrographic printing or copying device

摘要

In a system or method for development of potential images of images to be printed and generated on an intermediate image carrier using a developer fluid comprising charged toner particles and developer fluid in an electrographic printing or copying device, a feed device is provided comprising as function elements at least one chamber scraper, a raster element comprising cups to receiver the developer fluid, and at least one first flow element arranged in the chamber scraper. Between the at least one flow element and the raster element an electrical voltage is supplied such that a toner particle concentration in the cups of the raster element is increased. An application device accepts the developer fluid from the feed device and supplies it to the intermediate image carrier.
