Abstract
An image forming apparatus includes a belt rotating member forming, with the rotating member, a nip portion for fixing a toner image to the recording medium, first and second rollers rotatably supporting the belt rotating member, a stepping motor tilting the first roller, an output unit outputting an amount-of-rotation signal instructing an amount of rotation of a rotor in the stepping motor, an electric current control unit controlling electric current to be fed to a coil in the stepping motor based on the amount-of-rotation signal, and a notifying unit. The notifying unit provides a predetermined notification in a state that an image formation process can be executed based on an output from a detecting unit configured to detect a position of the first roller and a value counted by a measuring unit counting the amount of rotation instructed by the output unit.
