ABSTRACT:
A sheet supplying apparatus has a sheet stacking plate on which sheets are stacked, a drive unit for vibrating the sheet stacking plate upwardly and downwardly, and a sheet supply mechanism for supplying the sheet from the sheet stacking plate. A sheet supplying condition detecting device detects poor supply of a sheet bundle, and the drive unit is operated on the basis of a detection signal of the sheet supplying condition detecting device so that clogging of the sheets, poor sheet separation and poor sheet supply can be prevented.
