Abstract
A toner container according to one example embodiment includes a housing having a reservoir for holding toner. A first electrode and a second electrode are positioned on the housing. The first electrode and the second electrode form a capacitor having a capacitance that changes in response to a change in an amount of toner in the reservoir between the first electrode and the second electrode. The first electrode includes a first rod and the second electrode includes a second rod spaced from the first rod.
