Abstract
Un depósito de tóner que incluye un primer electrodo colocado dentro del depósito de tóner, un segundo electrodo conectado eléctricamente al primer electrodo y colocado dentro del depósito de tóner, y un electrodo sensor colocado entre el primer electrodo y el segundo electrodo. El electrodo sensor y el primer electrodo forman un primer capacitor que tiene una primera capacitancia que varía en respuesta a un cambio en la cantidad de tóner que existe entre los mismos. El electrodo sensor y el segundo electrodo forman un segundo capacitor que tiene una segunda capacitancia que varía en respuesta a un cambio en la cantidad de tóner que existe entre los mismos.
