Abstract:
A toner container including a first electrode disposed within the toner container, a second electrode electrically connected to the first electrode and disposed within the toner container, and a sense electrode disposed between the first electrode and the second electrode. The sense electrode and the first electrode form a first capacitor having a first capacitance that changes in response to a change in toner amount existing therebetween. The sense electrode and the second electrode form a second capacitor having a second capacitance that changes in response to a change in toner amount existing therebetween.
