Abstract:
A sheet feeding apparatus has a liftable stacking member on which a sheet is stacked, a feeding member which feeds the sheet in abutment against the uppermost one of the sheets placed on the stacking member, the feeding member moving from a separation position to an abutment position, a driving portion which lifts the stacking member, a sensor to detect that an uppermost sheet is below a predetermined position, and a control portion configured to control the driving portion so as to lift the stacking member when a signal from the sensor is received in sequence a plurality of times, which the control portion receives from a sensor due to the feeding member moving from the separation position to the abutment position repeatedly, indicate that the uppermost one of the sheets placed on the stacking member is located below a predetermined position.
