The transfer device allows a dosed quantity of the toner material to be fed from the supply reservoir (15) to the developer station (11) via a dosing cylinder (16) across the outlet of the supply reservoir (15). The toner material is supplied to the dosing cylinder (16) via a feed screw (20) within the supply reservoir (15) extending parallel to the cylinder axis, above the latter, with a coupled drive between the feed screw (20) and the dosing cylinder (16) determining the dosing rate. Pref. the feed screw (20) uses a spiral spring which is coupled to a central drive shaft (22) at one end and which is enclosed by an open sleeve (24) in the vicinity of the dosing cylinder (16). |
