摘要： A sheet feeding apparatus includes a sheet stacking unit, a suction conveyance unit configured to convey an uppermost sheet stacked on the sheet stacking unit, a suction unit configured to adsorb the sheets onto the suction conveyance unit, and an adsorption completion detection unit. In the sheet feeding apparatus, when the tab-attached sheets are stacked on the sheet stacking unit and fed such that their tab portions are on the downstream side in a sheet feeding direction, the suction unit starts to adsorb the sheet in response to a sheet feeding signal, and the suction conveyance unit starts to convey the sheet immediately after the adsorption completion detection unit detects the completion of the adsorption. When the sheets other than the tab-attached sheets are fed, the suction unit previously adsorbs the sheet onto the suction conveyance unit, and the suction conveyance unit starts to convey the sheet in response to the sheet feeding signal.
