摘要：
A plurality of moving-amount detecting units respectively detects a moving amount of the sheet fed by a feeding unit at a plurality of points in a width direction of the sheet. A skew detecting unit detects a skew of the sheet based on the moving amount of the sheet detected by the moving-amount detecting units.
