ABSTRACT:
A sheet feeding apparatus includes a sheet placing tray on which a sheet is placed, a feeding member for feeding the sheet placed on the sheet placing tray, a first sheet detection unit for detecting presence of the sheet on the sheet placing tray at a first detection position, and a second sheet detection unit for detecting presence of the sheet on the sheet placing tray at a second detection position disposed on an upstream side of the first detection position in a sheet feeding direction. A control unit controls the feeding member so as not to perform the sheet feeding operation when the first detection unit detects the sheet and the second detection unit does not detect the sheet.
