The image forming unit forms an image by using a developer, the cover is opened/closed to replace/cover the mounted container, the detector detects the mounted container in a cover closed/opened state, the controller determines whether a remaining amount of the developer in the container is more than a predetermined amount, and the display unit displays, in a case where the container in which the remaining amount is more than the predetermined amount is removed, a first screen promoting re-mounting of the container, a second screen on closing the cover without detecting the container after displaying the first screen, and a third screen after displaying the second screen in a case where the container is not mounted.
