    Abstract: An image forming apparatus includes a housing having an opening, a cover configured to openably close the opening, photosensitive drums, cartridges, a first motor and a controller. Each cartridge has a developing roller, a storage chamber configured to store toner, and an agitator configured to agitate the toner. The first motor is configured to rotate the agitators. The controller rotates the agitators by rotating the first motor when forming an image on a sheet. The controller determines whether a new cartridge is included in the plurality of cartridges in response to the image forming apparatus being turned on or in response to the cover being closed. In a case where a new cartridge is included, the controller stirs toner with the agitators by rotating the first motor. In a case where a new cartridge is not included, the controller does not stir the toner.
