<p>A curl eliminating device (18), which is constructed in a way that can cool the sheet and straighten the curl at the same time without having a large device and without increasing cost. The device has a transporting roller (18c), arranged in a sheet transporting passage; and a plurality of backup rollers (18A,18B), arranged abreast along a circumference of the transporting roller (18C). The backup rollers (18A,18B) press-contacts the transporting roller (18C) during rotating. The curl eliminating device clamps and transports the sheet in a way that the sheet conforms with the shape of the circumference of the transporting roller (18C). The backup rollers (18A,18B) are separately arranged along the circumference of the transporting roller (18C), and a separating distance is set to be changeable. The separating distance is set according to a curl amount of the sheet. <IMAGE></p> |
