A toner bottle has a main body, an opening, a gear, and an intermediate
area. The main body includes a guide used to guide the toner. The
intermediate area is located between the main body and the opening. Both
the main body and the intermediate area include a guide for guiding
toner. An angle of the guide of the main body relative to the axis of
rotation of the toner bottle is larger than an angle of the guide of the
intermediate area.
