摘要： A fixing device includes: a tubular member; a heater; a nip member; a stay; and a backup member. The heater including: a glass tube; and a heat source. The nip member confronts the heater in a confronting direction. The glass tube has an axis defining an axial direction. The glass tube includes a glass tube body having end portions in the axial direction and sealed portions formed integrally with the end portions. Each sealed portion is formed in a plate shape and protrudes radially outwardly from the glass tube body when viewing in the axial direction. Each sealed portion is oriented in a first direction and defines a cross-sectional distance between one end portion and another end portion of the sealed portion in the confronting direction greater than a cross-sectional length of the glass tube in a second direction perpendicular to the confronting direction and the axial direction.

The tubular member is circularly movable in a circularly-moving direction. The guide member has a part positioned upstream of the nip member in the circularly-moving direction and configured to guide the tubular member. The part has an end portion containing a most downstream end at which the tubular member is directed to a position between the nip member and the backup member. The nip member and the guide member define a first imaginary plane containing a line connecting a first curved portion provided by a boundary region between the connecting portion and the base portion, and the most downstream end. The first imaginary plane is positioned opposite to the heater relative to a first end of the flange portion.
