Abstract
An image forming apparatus prevents sheets from remaining inside the image forming apparatus even when a container that is not empty is replaced with another container. The image forming apparatus includes a mount to which a container containing developer is mounted, and a replenishing unit replenishing an image forming unit with the developer from the mounted container. In a case where the mounted container is replaced with another one without replacement of the container necessary during image formation of the image forming unit, a controller suspends feeding of a sheet, discharges the sheet remaining in a conveying path, and disables an image forming operation. A display displays a screen for prompting replacement of the mounted container if replacement of the container is necessary, and displays a screen for prompting re-mounting of the replaced container in a case where the mounted container is replaced without replacement of the container necessary.
