摘要：
A skew correction device includes a first conveying unit arranged in a sheet conveying path; a second conveying unit arranged downstream of the first conveying unit in a conveying direction of a sheet; and a skew correction unit. When the sheet is unfolded paper, the skew correction unit performs a first skew correction that corrects for the skew of the sheet so that a leading edge of the sheet conveyed by the first conveying unit abuts on the second conveying unit that is stopped. When the sheet is fold paper, the skew correction unit performs a second skew correction that corrects for the skew of the sheet so that a leading edge of the sheet conveyed by the first conveying unit abuts the second conveying unit and the second conveying unit is driven in a reverse direction to the conveying direction at a predetermined operational timing.
