Abstract
According to one embodiment, the image forming apparatus includes a developing device and a control unit. The developing device includes a rotator for rotating to cause a developer contained in a container to flow, and performs development using the developer. The control unit has a first control for rotating the rotator in a first direction during development. The control unit has a second control that rotates the rotator in a second direction opposite to the first direction at a predetermined timing when development is not performed. When the second control is performed a plurality of times during a predetermined period, the control unit gradually reduces an interval at which the second control is performed.
