Claim 0:
1. A heating device comprising:
a first rotator;
a heater configured to heat the first rotator, the heater including:
a base having one edge and the other edge in a longitudinal direction of the base; and
a heat generator being adjacent to the base and defining a heat generation area, the heat generation area having one edge and the other edge in the longitudinal direction, the one edge of the heat generation area being closer to the one edge of the base than to the other edge of the heat generation area,

the heater having a length between the one edge of the base and the one edge of the heat generation area in the longitudinal direction longer than a length between the other edge of the base and the other edge of the heat generation area in the longitudinal direction; and
a second rotator configured to contact an outer circumferential surface of the first rotator to form a nip, the second rotator having one edge and the other edge in the longitudinal direction, the one edge of the second rotator being closer to the one edge of the heat generation area than to the other edge of the second rotator,
the second rotator positioned to have a length between the one edge of the second rotator and the one edge of the heat generation area in the longitudinal direction shorter than a length between the other edge of the second rotator and the other edge of the heat generation area in the longitudinal direction.
