Abstract
An image forming apparatus includes an attachment portion, an attachment detection unit, an output portion, a first cover, a first detection portion, a second cover, and a control unit. A control unit is configured to control opening movement of the first cover to open the first cover linked with movement that the second cover is opened when the output portion outputs information of replacing the developer accommodating container. After the first detection portion detects that the first cover is in a closed state after the first cover has been opened based on information output by the output portion, the first detection portion detects whether the developer accommodating container is attached to the attachment portion or not, and if the first detection portion detects that the developer accommodating container is not attached to the attachment portion, the control unit controls the first cover to open.
