Abstract
A heating device includes a first rotator and a second rotator that contacts the first rotator to form a nip between the first rotator and the second rotator. A heater heats at least one of the first rotator or the second rotator. A first support frame supports one lateral end of the first rotator and the second rotator in a longitudinal direction of the first rotator and the second rotator. A second support frame supports another lateral end of the first rotator and the second rotator in the longitudinal direction of the first rotator and the second rotator. An incompatible member is mounted on the first support frame.
