PURPOSE:To enhance the efficiency of conversion of the toner container through an accurate detection, by detecting the full storage of the toner via the oscillator provided at the upper part of the toner container. CONSTITUTION:When the used toner collected into the container 3 via the screw coil 1 or the like becomes full in the container 3, the oscillation of the oscillator 4 of the piezoelectric ceramics or the like which is provided at the upper part of the container 3 and giving the resonance oscillation is suppressed and then stopped finally. Accordingly, the full storage of the toner can be detected accurately from the change of the oscillation output of the oscillating circuit using the element 4, thus increasing the converting efficiency of the toner container. As a result, a highly efficient collection of the toner becomes possible. |
