The sheet conveying apparatus includes a first curl forming part provided
downstream of a fixing part for fixing a toner image to a sheet, for
curling the sheet; a second curl forming part provided downstream of the
first curl forming part, for curling the sheet in a direction opposite to
a direction in which the sheet is curled in the first curl forming part,
in which a curling amount of the sheet in the second curl forming part is
set to be smaller than that in the first curl forming part, and the
curling amount of the sheet in the second curl forming part is variable
according to rigidity of the sheet. Thus, a shape of the curled sheet can
be reliably reformed with a simple structure.
