Abstract
The cleaning device for the drum-shaped intermediate image carrier of an electrophoretic printer is used in the field of technical data processing in order to improve the quality of the electrophoretically printed color images. The toner suspensions of different color used must be removed from the intermediate image carrier and must be separately applied to separate collecting reservoirs, one of which is provided for each toner suspension color. To this end, a ruler-shaped upper edge (5, 11) of an air duct (21) forms a narrow gap in conjunction with the intermediate image carrier (1). Therethrough air is forced in order to ensure that the toner suspension flows from the intermediate image carrier to a collecting reservoir (8) via a wiper (6) and a chute (7) of the cleaning device associated with each toner suspension. The chutes can be displaced so that accurate separation of the suspensions is ensured and each suspension is applied to the associated reservoir.
