Abstract
According to one embodiment, a heating device includes a belt and a heat generating member. The belt has a tubular shape. The heat generating member is provided inside the belt. The heat generating member is formed in an arc shape along the inner peripheral surface of the belt. The heat generating member is slidably in contact with the inner peripheral surface of the belt. When the amount of deflection of the belt is D, the radius of curvature of the inner peripheral surface of the belt is A, and the radius of curvature of the outer peripheral surface of the heat generating member is B, the following equations (1) and (2) are satisfied:≥10 mm  (1)0.4 mm≥≥0 mm  (2).
