Abstract

In a digital printer a developer element is provided that inks charge images on a charge image carrier with toner. A feed system is provided to apply liquid developer with the toner onto the developer element. The cleaning unit is provided with a cleaning element to clean off residual liquid developer remaining on the developer element after the development of the charge images. A scraping unit rests on the cleaning element made up of a double blade arranged in a blade mount. The double blade provides a cleaning blade and a sealing blade that together form a blade chamber that is filled with fluid. The cleaning blade has at least one row of holes adjacent to a blade edge of the cleaning blade.
