Abstract

This disclosure relates to a method of dispensing toner for use in an electrographic copier or printer. Toner dispenser 1, shown in cross-sectiona I view (Figures 1 and 21, comprises container 2, with an open bottom which is covered by Spandex fabric material 3. The container 2 contains toner 4 which is to be dispensed through the fabric 3 onto the appropriate developing mechanism located below the dispenser 1. Located inside the container 2 is an open-frame wire paddle 5. Paddle 5 is connected at pivot point 6 to a motivator (not shown) located outside the container. Figure 1 shows paddle 5 in the retracted position where it does not contact fabric 3. With paddle 5 in the retracted position, fabric 3 is in the non-stretched condition. Figure 2 shows paddle 5 pivoted on axis 6 into the dispense position. In this position, paddle 5 is pivoted by the motivator back and forth along fabric 3 so as to stretch fabric 3 and push toner 4 through the open holes in fabric 3 with a wiping action.
