Abstract: A device and method for storing toner within an image forming apparatus having an upper reservoir and a lower toner reservoir. A pass through region between the reservoirs may journal a rotatable metering bar. The bar may include convex depressions to dispense toner from the upper to the lower reservoir. The convex shape reduces the toner adherence to the bar, particularly in the case of chemically polymerized toner.

Abstract: The present invention relates to engagement or transfer of an image forming substance within a reservoir of an image forming apparatus. This may be achieved by a device such as a paddle that may include an additional component for engagement or transfer of the image forming substance. The component may be, for example, wire material. The component may also include a body section and an axially aligned projection.
