ABSTRACT:
Steady flow of dry toner from the discharge outlet of a toner tank is produced by inducing vortex-like motion of toner within the tank to inhibit toner bridging. A rotating brush associated with the discharge outlet has a rim in grazing contact with an edge of a fixed, inclined plate to establish the toner motion. In a preferred form of toner-supplying device, two discharge outlets are used, each associated with a brush/plate set.
