The heater is configured to radiate radiant heat. The nip member is configured to receive the radiant heat from the heater. The stay has an inner surface confronting the heater and an outer surface in opposition to the inner surface. The stay is configured to cover the heater and to support the nip member. The tubular flexible fusing member has end portions in an axial direction and an inner peripheral surface. The fusing member is configured to surround the heater, the nip member and the stay. The pair of frame members is disposed at the end portions. One of the frame members is formed with an inlet opening. Remaining one of the frame members is formed with an outlet opening. The inlet opening and the outlet opening are in fluid communication with a space defined between the inner peripheral surface and the outer surface. The backup member is configured to provide a nip region in cooperation with the fusing member upon nipping the fusing member between the backup member and the nip member. The ventilator is configured to allow an air to flow in the space in the axial direction from the inlet opening to the outlet opening.

摘要： A fixing device for thermally fixing a developing agent image to a sheet includes a tubular flexible fusing member, a nip plate, a heater, a reflection plate, and a backup member. The tubular flexible fusing member has an inner peripheral surface defining an internal space and an axis defining an axial direction. The nip plate is disposed in the internal space, and the inner peripheral surface is in sliding contact with the nip plate. 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 greater 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.
