摘要： A recording material processing apparatus includes a recording material supplying device supplying a recording material, an image recording device recording an image on the recording material, a recording material transporting mechanism and a burr curing device including a pressurizing member for curing the burrs at the edge of the recording material. The recording material transporting mechanism changes a transporting state of the recording material at a predetermined transportation changing position. The pressurizing member is provided on a recording material transporting path between the recording material supplying device and the transportation changing position and is provided on the side nearer to the recording material supplying device than a trailing end position. The trailing end position indicates a position of the trailing end of the recording material in the transporting path when a leading end of the recording material in the transporting direction passes the transportation changing position.
