An image forming apparatus includes a main body including a sheet transport
path having an output part and an image forming part for forming an image
on a sheet, and a sheet discharging device located in the vicinity of the
output part, and a sheet receiving part. The sheet discharging device
discharges the sheet having an image formed thereon by the image forming
part. The sheet receiving part receives the sheet discharged by the sheet
discharging device. The sheet discharging device includes a discharging
member, disposed in the vicinity of the output part, for transporting the
sheet in a nipping manner, a drive force transmitting mechanism for
driving the discharging member to rotate, and a discharge control unit for
controlling the drive force transmitting mechanism when the sheet passes
the discharging member so as to temporarily delay a time taken for sheet
discharging by the discharging member.
