ABSTRACT:
A sheet feeding apparatus has: a tray on which sheets to be fed are stacked; a sheet feeding portion which separates and feeds the sheets stacked on the tray one by one; and a sensor which discriminates a type of sheet. In a state in which one sheet of the sheets stacked on the tray is protruded from the tray by the sheet feeding portion, the sensor discriminates the type of the protruded sheet.
