Abstract: An image synthesizing apparatus includes a reading unit which reads an image of an original, and an input unit which inputs print data from an external apparatus. A first setting unit sets a synthesis mode for synthesizing image data output from the reading unit and the print data input from the input unit for recordation, and a second setting unit sets a number of pages of different print data to be synthesized in the synthesis mode. A control unit is adapted, when the synthesis mode is set by the first setting unit, to maintain the synthesis mode until the different print data of the number of pages set by the second setting unit is input by the input unit, and to cancel the synthesis mode after the different print data of the set number of pages has been input.

Abstract: An synthetic-image forming apparatus including: an interface for inputting image information from a computer; a scanner for inputting original document image information; an operation portion for inputting region information indicating a region in which images are synthesized; an operation portion for selecting a printer base mode in which the image information from the interface is synthesized onto outside of the region and image information from the scanner is synthesized onto inside of the region or a scanner base mode in which the image information from the interface is synthesized onto inside of the region and the image information from the scanner is synthesized onto outside of the region; image forming portion for synthesizing the image information from the interface and the image information from the scanner in accordance with the mode selected by the operation portion and the region information supplied from the operation portion and forming an image on a selected sheet in accordance with the synthes
