A sucking device having a fixed material transportation surface including plural sucking holes, a decompression chamber connecting to the plural sucking holes, and a sucking device sucking air in the decompression chamber is set at discharging side of the fixed material. The fixed material is fed on the fixed material transportation surface of the sucking device by the delivering device, and is stuck on the fixed material transportation surface through the sucking holes by the sucking device. The fixed material is fixed by a fixing head at the state being stuck and is transported gradually to a downstream side from an upstream side by the delivering device on the fixed material transportation surface. After that, when fixing is finished, the fixed material separates from surface of the fixed material transportation surface and rises slightly by blowing air from the sucking holes by a blowing device so as to move to discharging direction, that is, the downstream side by an auxiliary transporting device. Thus, since the fixed material is discharge smoothly, the prior discharging serrated roller is unnecessary so that spur mark run over caused by the discharging serrated roller does not remain on the fixed material at discharging.
