A controller sets a pressure-contact time from memory in accordance with rigidity of a sheet and starts a feeding operation of a sheet by causing a feeding roller to be pressure contacted with sheets on a sheet stacking plate. The controller controls the feeding roller to be separated from the sheets on the sheet stacking plate after passage of the pressure-contact time. In this way, it is possible to set the optimum pressure-contact time at the time of feeding sheets in accordance with the kind of sheet being fed and realize a stable feeding operation. Since the controller controls a driving unit based on a detection signal of a sheet-surface detecting flag that detects the height of the uppermost surface of a sheet bundle, it is possible to realize the stabilization and acceleration of a contacting operation.
