Abstract:
A powder-amount detection device includes a first electrode disposed on one side of a powder container to be replaceably installed to an image forming apparatus; a second electrode disposed adjacent to the first electrode and having a smaller surface area than the first electrode, an influence of an amount of powder in the powder container to a capacitance of the second electrode being as small as negligible; a third electrode disposed on a side opposite to the second electrode with the powder container interposed between the third electrode and each of the first electrode and the second electrode; and a voltage detector configured to detect charging and discharging behaviors of the first electrode and the second electrode when a voltage is applied between the third electrode and each of the first electrode and the second electrode for a short time, to detect the amount of powder in the powder container.

Claim (Index 3):
The powder-amount detection device according to  claim 1 , further comprising:\n a dielectric layer disposed on an outer side of the first electrode and the second electrode; and a driving electrode disposed at an outer side of the dielectric layer with the dielectric layer interposed between the driving electrode and each of the first electrode and the second electrode, wherein the voltage detector applies a voltage to the driving electrode for a short time to charge and discharge the first electrode and the second electrode.
