PROBLEM TO BE SOLVED: To provide a sheet postprocessor for an image forming device which prevents sheet matching from decreasing accompanying curl correction by the depression of a sheet on a bin. SOLUTION: The operation order of peripheral members of the bin 31 is combined and changed according to the state of a recording sheet P to be carried. Namely, it is recognized whether the recording sheet P is already curled when discharged to and mounted on the bin 31 or gradually curled after being discharged to and mounted on the bin 31. Operation periods such as the period of matching by a 1st matching guide plate 34 and a 2nd matching guide plate 35 and the period of curl correction by a sheet pressure member 37 are adjusted. |
