Abstract
A heating device includes: a rotating body; a heating body as defined herein; and a contact mechanism, in a non-existence state where a material to be heated does not exist between the rotating body and the heating body after the material to be heated passes between the rotating body and the heating body, configured to cause the rotating body to be in contact with the heating body at a central portion of the rotating body in a rotation axis direction of the rotating body, so that an area of the rotating body in contact with the heating body is smaller at each of both end portions of the rotating body than at the central portion of the rotating body in the rotation axis direction, or configured to switch the rotating body between a first contact state and a second contact state as defined herein.
