Image forming apparatus having a rotational portion which accommodates a developer

An image forming apparatus includes an accommodation container, a storage medium, and a controller. The accommodation container includes a rotational portion and outflow portion. The rotational portion accommodates a developer therein and has a helical-shaped transport section formed in an inner surface thereof. The outflow portion rotatably supports the rotational portion and has an outflow port through which the developer transported during rotation of the rotational portion flows out. The storage medium stores use state information of the developer accommodated in the rotational portion. The controller controls a driving source which drives the rotational portion. When a use state of the accommodation container for the developer is a use state which is set in advance, the controller intermittently drives the rotational portion by performing driving at a rotation angle of (n+½)π±18 degrees or less than 90 degrees and stopping.
