Abstract:
A sheet feeding device is provided to separate a sheet from a plurality of stacked sheets and feed the sheet. The sheet feeding device includes a sheet stacking portion on which the sheets are stacked, a suction conveyance belt which separates the sheets stacked on the sheet stacking portion, one by one and feeds the sheet, and a separation rotating roller which is rotatable upon abutting on a rear portion, in a feeding direction, of the sheets stacked on the sheet stacking portion. The separation rotating roller rotates in a direction which returns the sheet in synchronization with sheet feeding operation performed by the suction conveyance belt.
