An image forming apparatus which uses toner to form an image on a sheet may cause the sheet to experience curl after passing through a fixing device which uses heat and pressure to fix the toner image on the sheet. A pair of discharge rollers and/or a sheet separating board may be utilized to correct the curl on the sheet, for both thin and heavy paper weights. The angle of the sheet separating board relative to a line which is perpendicular to a sheet discharging direction is preferably set from 75° to 95°, and a nip depth of a pair of sheet discharging rollers is preferably set from 0 mm to 3 mm.
