Abstract
A sheet feeding device includes a stacking portion, a first roller, a second roller, a third roller rotatable to provide peripheral movement in a predetermined direction and to provide peripheral movement in a direction opposite to the predetermined direction, a detecting unit, a driving unit for executing a feeding operation by the first roller, and a control unit for providing an instruction to the driving unit so as to continue or stop the feeding operation. The predetermined rotational frequency is larger than 0 and is smaller than a rotational frequency of the third roller in a period in which the third roller is rotated in the predetermined direction in a state in which a single recording material is fed to the nip.
