Patent ID: 7832723

Claim:
A sheet feeding apparatus comprising: a feeding tray on which a plurality of record sheets are set; a first feeding member that feeds at least an uppermost record sheet from the feeding tray; a second feeding member that feeds the uppermost record sheet fed by the first feeding member; a separating member, wherein a nip portion is formed between the separating member and the second feeding member, and when the uppermost record sheet and at least one of the next record sheets overlapping each other enter the nip portion, the separating member separates the entered at least one of the next record sheets from the entered uppermost record sheet; an adjusting unit that changes a force of the separating member acting on the entered at least one of the next record sheets; a detecting unit that detects an advancing speed of the other of the entered record sheets at the nip portion; and a controller that controls the adjusting unit to enhance the force in a case where the advancing speed of the detecting unit exceeds a predetermined value, wherein the separating member has a separating roller rotating in a direction of pushing back the entered at least one of the next record sheets toward the feeding tray, and the adjusting unit changes a rotational torque applied to the separating roller.
