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 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.

摘要： In a fixing device, a nip plate is disposed on an inner surface of a tubular flexible fusing member which is flexibly deformable, and configured to be heated by a heating element disposed inside the fusing member. The fusing member is nipped between the nip plate and a backup member to form a nip portion. First and second portions of the nip plate which are located in positions upstream and downstream, respectively, with respect to a recording sheet conveyance direction and to be supported by a stay are each configured to be a flat plate extending along the recording sheet conveyance direction. A central portion between the first and second portions of the nip plate is in a position shifted from those of the first and second portions in a direction perpendicular to flat surfaces of the first and second portions.

摘要： An image forming device includes: a heater; a nip member; a stay; fusing member; a pair of frame members; a backup member; and a ventilator. The nip member receives radiant heat from the heater. The stay has an inner surface confronting the heater and an outer surface opposing the inner surface. The fusing member surrounds the heater, the nip member and the stay. The pair of frame members is disposed at end portions of the fusing member. One frame members is formed with an inlet opening. The remaining frame member is formed with an outlet opening. The inlet and outlet openings are in fluid communication with a space between an inner peripheral surface of the fusing member and the outer surface. The backup member provides a nip region upon nipping the fusing member between the backup and nip members. The ventilator allows air to flow in the space.
