    • 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.
    • 定影装置包括加热器,旋转固定构件和按压旋转固定构件的旋转按压构件,以在其间形成带有调色剂图像的记录介质通过该辊隙以在其上固定调色剂图像的辊隙。 定影装置包括一个空气供应管,其沿着记录介质的输送方向设置在压区的下游,并连接到图像形成装置的空气源,以将压缩空气供给到设置在供气管上的多个喷嘴 辊隙的长轴垂直于输送方向,并将脉冲压缩空气喷射到通过辊隙的记录介质上。 空气供给管包括设置在靠近空气源的记录介质通过区域外的压缩空气流的最上游端的排气口。
