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.
