A heater is disposed in the internal space and confronts the nip plate in a confronting direction. The heater includes a glass tube, a heat source provided in the glass tube, and a gas sealed in the glass tube. The glass tube includes a glass tube body and a tip portion protruding radially outwardly from the glass tube body for sealing the gas in the glass tube body. The tip portion protrudes in a predetermined direction to define a cross-sectional length of the glass tube in the confronting direction smaller than a cross-sectional length of the glass tube in a perpendicular direction extending perpendicular to the confronting direction and the axial direction, and the cross-section includes the tip portion. The reflection plate is configured to reflect a radiant heat from the heater toward the nip plate. A backup member is configured to provide a nip region in cooperation with the nip plate for nipping the fusing member between the backup member and the nip plate.
