ABSTRACT:
A developing apparatus is arranged so that a toner container having an opening portion which can be opened or closed is engaged with a toner replenishing opening of a toner hopper so as to open the opening portion of the toner container. A rotary shaft extends through the toner container, has a toner stirring member mounted thereto, and is coupled with a driving shaft of an agitator. When rotated by the driving shaft of the agitator, the rotary shaft causes the toner in the toner container to drop into the toner hopper due to rotation of the stirring member within the toner container, which rotates simultaneously with the agitator in the hopper.
