ABSTRACT:
An image forming apparatus has an image forming unit that forms an image on a sheet; a discharging roller pair that discharges the sheet, on which the image is formed, onto a stacking portion with a rotation in a first direction, and conveys the sheet to a re-conveying path for conveying the sheet to the image forming unit again with a rotation in a second direction opposite to the first direction; and a skew feed correction member that is provided in the re-conveying path, and contacts against a leading edge of the sheet conveyed by the rotation in the second direction to correct skew feed of the sheet. The sheet conveying force when contacting the leading edge of the sheet against the skew feed correction member is smaller than sheet conveying force of the discharging roller pair when discharging the sheet onto the stacking portion.
