Abstract

PURPOSE:To obtain a simple device for remedying a curl in a sheet, by providing a control means for controlling a humidity regulating means in accordance with an output from a sheet curl amount measuring means. CONSTITUTION:After fixation, the amount of a curl in a sheet is detected by a curl amount measuring device 25 in a curl detecting section. Further, data concerning the curl amount and the direction of the curl are delivered from the curl amount measuring device 25 to a signal generating device 38 to which data of curl levels for trays are inputted from a curl lever tolerance setting device 39, and from which an excessive curl amount signal and a curl direction signal are delivered in accordance with the inputted data. These signals are delivered to a heater control device 40 so that heaters 41 are controlled for turn-on and -off, thereby it is possible to remedy the curl of the sheet. Further, the signal generating device 38 is additionally provided with a humidity control device.
