Abstract

A technique is provided that can realize highly accurate skew correction without employing any particularly complicated device configuration. The quantity of skew of a sheet is determined in accordance with a detection result from a first pair of sensors. Driving of each of first rollers and second rollers is separately controlled to carry the sheet in such a manner as to reduce the quantity of skew determined in accordance with the detection result from the first pair of sensors. The quantity of skew of the sheet is determined in accordance with a detection result from a second pair of sensors. Driving of each of the first rollers and the second rollers is separately controlled to carry the sheet in such a manner as to reduce the quantity of skew determined in accordance with the detection result from the second pair of sensors.
