Abstract
A heating device includes a first rotator, a heater including a base and a heat generator, and a second rotator contacting the first rotator. The heat generator adjacent to the base defines a heat generation area having one edge close to one edge of the base in a longitudinal direction of the base. A length between the one edge of the base and the one edge of the heat generation area is longer than a length between the other edge of the base and the other edge of the heat generation area. The second rotator has one edge close to the one edge of the heat generation area. A length between the one edge of the second rotator and the one edge of the heat generation area is shorter than a length between the other edge of the second rotator and the other edge of the heat generation area.
