摘要：
A sheet feeding apparatus provided with a fan for blowing air against sheets stacked on a sheet tray, a position detecting sensor for detecting the position of the sheets floated up by the fan, and a tray lifting and lowering mechanism for lifting and lowering the sheet tray. The tray lifting and lowering mechanism is controlled on the basis of a result of detection by the position detecting sensor.
