Claim:
A fixing device configured to thermally fix a developing agent image to a sheet fed in a sheet feeding direction, the fixing device comprising: a tubular flexible fusing member having an inner peripheral surface defining an internal space and configured to be circularly movable; a heater disposed in the internal space and configured to radiate a radiant heat; a nip member disposed in the internal space, the inner peripheral surface configured to be in sliding contact with the nip member; a reflection member configured to reflect the radiant heat from the heater toward the nip member, the reflection member including a reflection portion and an extending portion; a stay configured to cover the reflection portion and to support the nip member, the extending portion extending outside of the stay; and a backup member configured to provide a nip region in cooperation with the nip member upon nipping the tubular flexible fusing member between the backup member and the nip member, wherein the extending portion extends between the nip member and the stay, and wherein the extending portion is positioned exclusively downstream of the reflection portion in the sheet feeding direction.
