Abstract: Disclosed is a sheet discharging apparatus including a charge eliminating member which is provided downstream a pair of swinging rollers for discharging a sheet, and is directed along a sheet discharging direction from its upstream side toward its downstream side. In the sheet discharging apparatus, the charge eliminating member is directed along the sheet discharging direction from its upstream side toward its downstream side, so that an area of the charge eliminating member facing a sheet is made larger than that of a conventional one, and static electricity of the sheet can be surely removed. Particularly, even when the sheet is a color sheet on which a color image charged with more static electricity than a monochromatic sheet is formed, the static electricity of the color sheet can be surely removed.
