To solve a problem that a method for previously deciding the paper ejection form of an ordinary printed matter and that of a printed matter by interruption printing so as to easily sort the printed matter is not always an effective means because the size of the printed matter is various.
The image forming apparatus stores the paper ejection form adopted for ordinary printing interrupted by the interruption printing. When the interruption printing is designated, the image forming apparatus adopts the paper ejection form different from the stored paper ejection form as the paper ejection form for the interruption printing. By adopting the paper ejection form different from the paper ejection form adopted for the ordinary printing, the paper ejection form adopted for the interruption printing is surely made to differ from that for other printing even when it is not stored in advance.
