A sheet feeding apparatus includes a control unit. After finishing feeding the sheet, if the sheet detection unit does not detect the sheet when the lift plate is positioned at the sheet feeding position, the control unit sets the waiting position to a lowest position. Further, if the sheet detection unit detects the sheet and if the remaining amount detection unit detects that the remaining amount of the sheets is a predetermined amount or less, the control unit sets the waiting position to a height position between the sheet feeding position and the lowest position. Further, if the sheet detection unit detects the sheet and if the remaining amount detection unit detects that the remaining amount of the sheets is more than the predetermined amount, the control unit sets the waiting position to the lowest position.
