Abstract
In order to prevent clogging of the nozzle and to ensure that the intermediate image carrier (8) is uniformly wetted with toner suspension across its entire width directly at the beginning of the printing operation, the nozzle comprises a front chamber (3) which extends across the entire width of the intermediate image carrier (8). Toner suspension enters said front chamber and subsequently reaches, via narrow bores (4), an open rear chamber (5) which is filled with suspension as far as an overflow edge (6). At the beginning of the operation, the suspension flows over the edge (6), across an inclined surface (7) in order to be applied to the intermediate image carrier (8) in a film of given thickness. The thickness of the suspension film is determined by a gap (10) which is formed by the nozzle and the intermediate image carrier (8). The nozzle has a flat shape, so that several nozzles can be arranged over one another.
