Abstract
A sheet which entered between a first sheet conveying unit and a second sheet conveying unit is detected by a sheet detecting unit. A loop of the sheet formed with a difference of sheet conveying speeds between the first and second sheet conveying units is detected by a loop detecting sensor. After the sheet detecting unit detected the sheet, if the loop detecting sensor does not detect the loop, a control unit which controls the sheet conveying speed of at least one of the first and second sheet conveying units controls the sheet conveying speed of at least one of the first and second sheet conveying units, thereby reducing an amount of the formed loop.
