ABSTRACT:
A developer supplying apparatus of the present invention includes a toner bottle, a bottle supporting member that is in the shape of substantially a cylinder, and a shutter mechanism for opening and closing a toner discharging opening formed on the bottle supporting member. The shutter mechanism includes (i) a shutter member which is slidably provided on the bottle supporting member and opens/closes the toner discharging opening, and (ii) a protruding portion which is provided on the toner bottle, and when the shutter member is located at such a position that the toner discharging opening is closed, engages with a part of the shutter member so as to stop rotation of the toner bottle. Thus, it is possible to realize the developer supplying apparatus which can stably supply a toner to a development device at high speed.
