A heating device includes a first rotating member and a second rotating member revolving in contact with the first rotating member. The second rotating member heats a passing recording medium having a toner image and held between the first and second rotating members, thereby fixing the toner image on the recording medium. The heating device further includes a pair of supporting plates supporting the first and second rotating members by being arranged on both sides across the first and second rotating members in a width direction crossing the passing direction of the recording medium. The supporting plates each have a tabular section with a first surface facing the first and second rotating members. The heating device further includes a resistance element arranged on a second surface side opposite to the first surface of the tabular section, and representing the type of a fixing device by using resistance.
