Device for erasing and cooling a sheet

A method for cooling a sheet comprising the steps of:

• conveying, on a conveyance path, the sheet from a first unit to a second unit, the conveyance path including a curved portion between the first unit and the second unit;
• and
• cooling, with a cooling unit, the sheet which passes through the conveyance path, the cooling unit including at least one fan that supplies cooling air generally along a sheet conveying direction, wherein an outer air flow rate of the cooling air supplied to an outer peripheral portion of the curved portion of the conveyance path is larger than an inner air flow rate of the cooling air supplied to an inner peripheral portion of the curved portion of the conveyance path.
