  • Image forming apparatus capable of forming at least one input image on at least one sheet surface and also of forming a selected prestored image on an otherwise blank surface of the sheet
    Patent number: 7369785
    Abstract: At forming an image only on one side of a sheet, an image forming unit is controlled by a control unit to form a back-side pattern image on the back side of the sheet. At forming images on both sides of sheets, when a blank side where no image is formed exists, similarly, the back-side pattern image is formed on the blank side. In single-sided printing, a back-side pattern image is formed on the back side of the sheet. In double-sided printing, a predetermined image is formed on a blank page and thus no blank page occurs. It is therefore possible to prevent the back side of a sheet on which an important document is printed from being used for other purpose, and consequently security is enhanced.
