A sheet feeding device can perform registration of a sheet with high precision even if the sheet is fed at high speed. The device includes a pair of active registration rollers, disposed at a side upstream from a reading unit in the sheet feeding direction, for correcting skew of the sheet, skew-amount detection sensors, disposed at a side downstream from the pair of active registration rollers in the sheet feeding direction, respective pairs of feeding rollers, disposed at a side upstream from the pairs of active registration rollers in the sheet feeding direction, and sheet detection sensors, disposed at a side upstream from the pairs of feeding rollers in the sheet feeding direction. Each of the pairs of feeding rollers includes a roller having a semispherical cross section at the driving side. When the leading edge of the sheet has been detected by the sheet detection sensors, the semispherical rollers are stopped in a state of not holding the sheet when the sheet is fed to the pair of active registration rollers by rotating the semispherical rollers by a predetermined number of revolutions at the same phase.
