Abstract
An image forming apparatus includes a waste toner container for containing toner recovered from a photosensitive drum and an intermediate transfer belt. The waste toner container has a stirring screw for conveying the toner in the waste toner container. The stirring screw is driven by a waste toner motor. A CPU determines whether the waste toner container is in need of replacement depending on a rotation speed or driving current of the waste toner motor. If the waste toner container is in need of replacement, the CPU displays such on a display unit to provide a notification to a user.
