Abstract:
PROBLEM TO BE SOLVED: To provide a sheet determination device that can appropriately determine the curled state of a sheet to be ejected.SOLUTION: Ejection rollers 51 and 57 eject a sheet on which an image is formed. A fullness detection sensor 54 detects the height of the sheet being ejected by the ejection rollers 51 and 57. A control part determines the curled state of the sheet ejected by the ejection rollers 51 and 57 on the basis of a result of detection from the fullness detection sensor 54. The control part detects that, with the fullness detection sensor 54, the height of the sheet being ejected by an arm part 58 is higher than a predetermined height and determines the curl of the sheet sandwiched by a sandwiching part N2.SELECTED DRAWING: Figure 3
