ABSTRACT:
A curved conveying guiding portion which guides a sheet toward a skew correcting unit is provided on a sheet conveying direction upstream of the skew correcting unit which corrects a skew of the sheet by rotating the sheet while conveying it. By narrowing an interval in the vertical direction in a center portion in the lateral direction of the conveying guiding portion, when a sheet S is rotated and corrected by the skew correcting unit, a load which the sheet to be corrected receives from the conveying guiding portion is reduced.
