ABSTRACT:
A sheet feeding apparatus enables the uppermost sheet in sequence in a stack of recording papers be lifted by air flow to separate and to convey the recording paper. The feeding apparatus comprises a laying plate on which plural sheets are stacked, a sheet feeding means disposed above the stacked sheets, which means partially deforms the first sheet in sequence by negative pressure at the leading end part of the sheet, and air forming means which injects air flow between the first sheet and the next sheet near the both ends in the widthwise direction of the recording paper, which flow comprises a straightforward air flow, and an air flow directed outwardly in the widthwise direction. The recording paper is separated from the next sheet by the air flow.
