PROBLEM TO BE SOLVED: To improve waving of a sheet in which an end part in width direction has expanded more in transportation direction than around a center.SOLUTION: There are provided a first roller pair which includes a first roller and a second roller, to transport a sheet by pinching it with a first nip part, a second roller pair which includes a third roller and a fourth roller, to pinch and transport the sheet that is transported by a second nip part of the first roller pair, and load means which applies a tensile in transportation direction on a sheet that is pinched and transported by the first nip part and the second nip part. The first roller is different from the second roller in terms of hardness, and the third roller is different from the fourth roller in terms of hardness. |
