Zusammenfassung:	The image forming apparatus includes a communication unit, a sheet feed unit, a printing part, a storage unit, an operation part, and a control unit. With an economy mode set, the control unit selects, as first document data, one piece of document data out of document data stored in the storage unit. The control unit makes a comparison between the first document data and newly received second document data. The control unit recognizes a missing portion that is present in the second document data but absent in the first document data. The control unit generates missing-and-added image data for printing of only the missing portion. The control unit instructs for feeding sheets of a set printed matter based on the first document data and for executing printing based on the missing-and-added image data.
