- a heating rotator to heat a medium;
- a heat source including:
- a glass tube disposed inside the heating rotator to generate radiant heat;
- and
- a sealing on each of both ends of the glass tube in an axial direction of the heating rotator;
- a heater holder to hold the heat source inside the heating rotator;
- a support having an outer diameter smaller than an inner diameter of the heating rotator to support the heater holder inside the heating rotator;
- and
- a gas supply disposed outside an outer end of the heating rotator in the axial direction, the gas supply to supply gas to the sealing through the support in the axial direction,
- wherein the heating rotator has an air hole facing the sealing, and
- the air hole discharges the gas blown to the sealing from the air hole in a transverse direction orthogonal to the axial direction.
