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.
