摘要： In a fixing device for thermally fixing a developer image transferred onto a recording sheet, a nip plate is disposed on an inner surface of a tubular flexible fusing member which is flexibly deformable in such a manner that permits the fusing member to slide along the nip plate, 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 between the fusing member and the backup member. The nip plate is bent to form a recessed portion which opens on the inner surface of the fusing member and holds a lubricant.

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.

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.
