Abstract

In a method or device for dosing toner material in an electrophotographic printer or copier, toner material is introduced into at least one bucket chamber rotatably arranged in an opening at a bottom of a toner reservoir. The bucket chamber has a paddle wheel which seals the opening of the toner reservoir. As the paddlewheel rotates, toner material in the bucket chamber is conveyed into a region. The toner material conveyed from the paddlewheel is further conveyed with a screw conveyor. Also a toner reservoir is provided having a toner removal opening shaped to accommodate at least a portion of a paddlewheel.
