After a two-component developer with known toner concentration is poured into a tank and begins to be stirred, its toner density is measured quickly at least three times by a toner density sensor and the final value to which the output of this sensor is expected to converge is calculated from these measured values such that a reference value by which the supply of toner is controlled can be estimated much more quickly than by waiting for the output of the sensor to stabilize. |
