Toner supplying device

摘要

A toner supplying device of the present invention has a toner storage tank having a toner supply opening in its bottom for accommodating a toner therein; a first toner transport member disposed within the storage tank and drivingly rotatable for transporting the toner; a second toner transport member disposed within the storage tank in parallel with the first toner transport member and drivingly rotatable for transporting the toner in a direction opposite to the direction of transport by the first toner transport member; and a cover covering the first toner transport member and the toner supply opening, yet only partially covering the first toner transport member. With this device, an excess of toner is prevented from flowing out from the storage tank through the opening since the cover is provided at an intermediate portion of the path of transport of the toner for covering the first toner transport member and the toner supply opening.
