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.

摘要： A fixing device includes: a tubular member; a heater; a nip member including a base portion, a connecting portion, and a flange portion; a backup member; and a guide member. 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.

摘要： There is provided a fixing device for thermally fixing a developing agent image to a sheet. The fixing device includes a tubular flexible member, a heater, a nip member, a reflection plate, a backup member, a stay and a temperature sensor. The flexible member has an inner peripheral surface defining an internal space. The heater is disposed in the internal space and is configured to generate a radiant heat. The nip member is disposed in the internal space, the inner peripheral surface being in sliding contact with the nip member. The reflection plate is configured to reflect the radiant heat from the heater toward the nip member, the reflection plate having an outer profile. The backup member is configured to provide a nip region in cooperation with the nip member for nipping the flexible member between the backup member and the nip member. The stay covers the reflection plate and supports the nip member, the stay having a profile in conformance with the outer profile of the reflection plate, and the stay being formed with one of a through-hole and a notch. The temperature sensor is disposed in the internal space and extends through the one of the through-hole and the notch.
