摘要：
To provide a technique for reducing waste of thermal energy in a fixing device. The fixing device includes: a heating rotational unit configured to heat a sheet on which a toner image is formed; a pressing rotational unit configured to come into press contact with the heating rotational unit to form a nip between the heating rotational unit and the pressing rotational unit and nip and carry the sheet in cooperation with the heating rotational unit; a heating device configured to heat the heating rotational unit; and a heat accumulating unit configured to cover at least a range above at least one of the heating rotational unit and the pressing rotational unit.
