In a recirculating feeder of sheets, the sheets are supplied and restored by the top-pick bottom-return method from a storing device in which the sheets are stacked and stored. The sheets are restored in the lowermost position in the stacking direction of the stacked sheets and stored in the storing device through a driving member, a first restoring device and a second restoring device. The driving member is controlled so as to approach/depart from the first restoring device, and when the sheet is conveyed into the storing device, it approaches to intervene between the lowermost position in the stacking direction of the sheets and the first restoring device, thereby pinching the sheet together with the first restoring device. In this way, the conveying force of the first restoring device is securely transmitted to the sheet, and repelling and mixing are avoided. The driving member contains defining members, which are intended to match the sheet stacking. When the sheet is conveyed to the second restoring device, the driving member is departed. The second restoring device is controlled so as to intermittently contact with or depart from the sheet after the first restoring device, and conveys the sheet up to the final storing position. Thus, without lack of the conveying force, the sheet is securely restored, and soiling of the sheet is lessened by the intermittent contact.
