A sheet feeding apparatus for image processing systems such as a stencil duplicating machine or a copying machine comprises a sheet feeding time sensor, and a control unit. The control unit compares a sheet feeding time detected by the sheet feeding time sensor with a predetermined reference sheet feeding time, and controls a revolution speed of a sheet feeding roller during or after a sheet feeding operation.
