ABSTRACT:
A controller determines the degree of acuteness of the resonant oscillation of a piezoelectric oscillator, based on the developer's fluidity detection data detected by the piezoelectric oscillator. The toner density output data detected by a toner density sensor is modified to a correct value, based on the degree of acuteness, and a supply roller is controlled based on this corrected value so as to implement the necessary toner supply.
