    摘要: A fixing device includes a heater, a rotary fixing member, and a rotary pressing member pressing against the rotary fixing member to form a nip therebetween through which a recording medium bearing a toner image passes to fix the toner image thereon. The fixing device includes an air supply tube disposed downstream from the nip in the direction of conveyance of the recording medium and connected to an air source of an image forming apparatus, to supply compressed air to a plurality of nozzles disposed on the air supply tube along a long axis of the nip perpendicular to the direction of conveyance and inject pulsed compressed air against the recording medium passing through the nip. The air supply tube includes an exhaust opening disposed at an extreme upstream end of the flow of the compressed air outside the recording medium passing area near the air source.

    摘要: A sheet separating device is attached to a fixing device. The fixing device includes: a fixing member that is a rotary body having a heating unit; and a pressing member that is pressed against and is brought into contact with the fixing member. The fixing device conveys a sheet material that carries unfixed toner thereon through a nip section formed by the fixing member and the pressing member so as to fix the unfixed toner image to the sheet material. The sheet separating device includes: at least one nozzle member that discharges compressed gas from the direction of a nip outlet toward the nip section along the fixing member. The nozzle member is rotatably supported by a shaft member that is provided parallel to the fixing member and includes a gas flow passage through which compressed gas is supplied to the nozzle member.
