An image forming apparatus includes a toner container attaching unit to which a toner container is to be attached, the toner container attaching unit including an apparatus-side terminal that comes into contact with a container-side terminal of the toner container and an apparatus-side coupling that engages with a container-side coupling of the toner container, and a control unit. The control unit is configured to execute a first process to acquire information of the toner container via the apparatus-side terminal, and cause the apparatus-side coupling to be rotated based on a result of the first process.
