Summary:A sheet feeding apparatus and an image forming apparatus which can certainly feed sheets without being influenced by an aging change of fan characteristics are provided. An air is blown to sheets stacked on a tray by an air blowing mechanism having a plurality of fans which are independently rotated, thereby loosening the sheets. Prior to starting the feeding of the sheet, rotational speeds of the fans of the air blowing mechanism are controlled so as to be set to target rotational speeds which have been preset every plural fans so that a wind pressure which can loosen the sheets in the driving state of all fans is obtained.
