ABSTRACT:
A sheet feeding apparatus capable of obtaining a sufficient conveying force for pulling back double-fed overlapping sheets to a stacking tray side. A sheet feeding member feeds sheets incoming from a stacking tray which stacks the sheets into a conveying pass. A separating member separates the sheets fed to the conveying pass by the sheet feeding member one by one. A double feed detection sensor generates an output for detecting double feed of sheets fed to the conveying pass. A rotatable member contacts the fed sheet. A driving unit rotationally drives at least the rotatable member in a rotational direction for reverse feeding of sheets. A control unit controls the driving unit when the double feed of sheets is detected based on the output of the double feed detection sensor, such that the rotatable member is rotationally driven in the rotational direction for reverse feeding of sheets.
