Abstract
In an image forming apparatus, a toner container is provided for stocking a toner. In a body of the image forming apparatus, an opening is provided for supplying the toner to the toner container, and an opening cover for closing the opening when the toner is not supplied to the toner container. In the toner container, a rotator is provided so as to discharge the toner from the toner container into a developing device via a toner feed device. Moreover, the image forming apparatus includes an opening cover detector and a control section. The opening cover detector detects whether the opening cover is opened, and the control section prevents the rotator from driving when the opening cover detector detects that the opening cover is opened.
