Paper feeding apparatus
 A separation mechanism part is provided wherein a negative pressure to suck a recording paper apart from a stack is obtainable by contacting an uppermost sheet of the recording paper using a suction head, air flow into the suction head being cut off by contact of the suction head with the first sheet of the recording paper. The recording paper is sucked and separated one sheet by one sheet by bringing up the suction head, as such, by the negative pressure. This paper feeding apparatus can feed recording paper surely separated sheet by sheet, and even though the amount of piling of the recording paper in the piled state changes, the separating force applied to act on the uppermost sheet of recording paper when suction is applied is kept small and uniform.
