Abstract
An image forming apparatus includes a developing device including at least one stirring rotator configured to stir a developer in the developing device, a driver configured to drive the at least one stirring rotator in forward and reverse rotation, a device detector configured to detect whether the developing device is set in the image forming apparatus, and control circuitry configured to execute a warm-up operation. In the warm-up operation, the driver drives the at least one stirring rotator alternately in the reverse rotation and the forward rotation in response to a detection of setting of the developing device in the image forming apparatus by the device detector and a detection of a predetermined condition.
