摘要：
An image forming apparatus has: pluralities of sheet storage units; a printing unit; a sheet driving unit that feeds a sheet of paper from the sheet storage units to the printing unit; a group setting maintaining unit that forms a group of the sheet storage units; a residual sheet amount detecting unit that detects sheet empty on any of the sheet storage units in the group; a sheet storage switching control unit that controls the sheet driving unit to select another one of the sheet storage units in the same group for feeding a sheet, if the residual sheet amount detecting unit detects the sheet empty; and a sheet empty warning unit that warns a user of the sheet empty detected by the residual sheet amount detecting unit.
