Abstract
A device for removing deposits from the surface of a photoconductive element which is installed in an electrophotographic copier, facsimile machine, printer or similar image recorder. A rotatable fur-brush is movable into contact with the photoconductive element for removing deposits from the latter. The fur-brush is supported by an arm which is angularly movable between an operative position and an inoperative position assigned to the fur-brush. The arm is in turn driven by a pressing lever. When the image recorder is to start on a copying operation, the deposit removing operation is interrupted immediately. In a further embodiment, the fur-brush may also be movable in a reciprocating motion in the axial direction.
