Abstract
An image forming apparatus includes a toner storing portion, a stirring member that stirs the toner by rotating inside the toner storing portion, a driving unit for rotating the stirring member in a first rotation direction and in an opposite second rotation direction. A control portion controls the motor such that a rotation direction of the stirring member is changed from the first rotation direction to the second rotation direction, and a detection unit that detects a rotation state of the motor, wherein the control portion determines whether to end the rotating operation or not based on the rotation state detected by the detection unit, and wherein the rotation state includes a rotation speed or a rotation amount of the motor.
