Abstract:
A sheet feeding apparatus which includes: a sheet loading tray for stacking sheets; a suction and conveyance section placed above stacked sheets on the sheet loading tray and sucks and conveys a sheet in the sheet conveying direction; an air blowing section which blows air at the stacked sheets on the sheet loading tray and causes the sheet to float up; a skew correction section which is provided with a pair of conveyance rollers, and corrects a skew of the sheet being conveyed by the suction and conveyance section; and a control section which controls a force of sucking the sheet, wherein the control section changes the force of sucking the sheet from a first level to a second level that is lower than the first level, before a leading edge of the sheet butts against a pair of conveyance rollers of the skew correction section.
