Abstract
A heating device includes a rotator, a fan, an introduction duct, a cooling duct, and a movement mechanism. The rotator has a heater inside thereof. The fan is configured to generate an airflow towards a surface of the rotator. The introduction duct is positioned with respect to the fan and shaped such that the airflow is directed towards and is incident on a first end portion of the rotator in an axial direction of the rotator. The cooling duct extends between the introduction duct and a first end of the rotator in the axial direction, and faces the first end portion of the rotator. The cooling duct includes a plurality of duct portions extending along the rotational axis. The movement mechanism is configured to move the fan, the introduction duct, and at least one of the duct portions of the cooling duct along the rotational axis.
