Abstract

PURPOSE:To supply toner of uniform particle size stably by forming a small chamber surrounded with a partition wall and a toner supply roller and a supply chamber provided with an agitator member for supply toner to the small chamber in a toner hopper. CONSTITUTION:The inside of the toner hopper 22 is partitioned into the small chamber 26 surrounded with the partition wall 25 and toner supply roller 12 and the supply chamber 27, and the agitator member 23 is arranged in the supply chamber 27. Then fresh toner is supplied from the supply chamber 27 according to the rotation of the agitator member 23 as the toner is consumed in the small chamber 26. Thus, the fresh toner is charged and development is carried out repeatedly; and then toner of smaller size is consumed preferentially in the initial stage and the means particle size of the toner in the small chamber 26 increases gradually, but when the mean particle size of the toner consumed for development from the small chamber 26 increases up to the means particle size at the time of supply, the mean particle size of the consumed toner balances with the mean particle size of the supplied toner.
