Abstract:
A sheet feeding apparatus and an image forming apparatus are provided. When sheets are adsorbed to an adsorption conveyance belt, a suction shutter is switched from a block position to block a negative pressure to an adsorption position to adsorb the sheets by the negative pressure. When the sheets conveyed in an overlapping manner reaches a predetermined number and the next sheet is adsorbed, the timing to switch the suction shutter to the adsorption position is delayed compared to the timing at which a preceding sheet adsorbed in advance and a subsequent sheet overlap.
