Abstract

A device for dosing powdery bulk material, especially toner powder in electrophotographic devices, by means of a roller as a cell wheel, supported with a horizontal axis rotatably at the bottom of a reserve container, and which is fed with material in bulk with the help of a vibrating device, characterized in that the dosing roller, provided on its wrapping surface with at least one groove-like groove and that, as a consequence of its box-free assembly, forms the hermetic lower closure of the tray of the reserve container, it is in contact with brushes in the form of strips mounted in a displaceable manner, in the direction towards the dosing roller, equipped with exactly flat and running brushing surfaces parallel to the axis of the dosing roller, one of them mounted, with a length corresponding to the dosing roller, above said roller, on whose surface The casing exerts a slight pressure, and inside the reserve container, seen in the direction of rotation of the dosing roller, in front of the slit formed by the casing surface and the wall of the trough, while the other, with a length corresponding to the groove-like groove, is arranged elastically below the dosing roller and only presses against the envelope surface with one of its longitudinal edges, and because immediately above, and axially parallel with the dosing roller, there is a shaker bar equipped with transverse radii and elastically supported on the front walls, which is periodically moved back and forth.
