Image forming apparatus for forming image on tab-sheet

摘要

An image forming apparatus capable of printing images on tab-sheets as well as on normal sheets can automatically perform a mixed printing job including image printing for the normal sheets and image printing for the tab-sheets. The apparatus makes it possible to use image information a number of times and that preparation of the image information is easy. In the apparatus, image information of a text sheet document to be printed on the text sheets and image information of a tab-sheet document to be printed on the tab-sheet are separately inputted to the apparatus and separately stored in an image memory in advance. The apparatus performs combined printing in which printing of the image information of the text sheet document stored in the image memory and printing of the image information of the tab-sheet document stored in the image memory are so combined that the printings of the pages of the tab-sheet document are inserted intervening in the printing of the text sheet document at designated page positions.
