Abstract
A document is made which consists of a large number of recording sheets whose originality can be certified with reliability. Different specific images are respectively formed on a plurality of recording sheets of recording sheets outputted in constant order. Confirmation holes are formed on recording sheets at higher levels than the recording sheets with the specific images formed thereon, in positions in conformity with the positions of the specific images. When a document made by stacking those recording sheets is seen from the top, and the specific images are visible through the confirmation holes, the originality of the document can be certified. When the specific image is invisible through the confirmation hole, it is found that the document has been changed due to missing of part of the recording sheets, a change in order of the recording sheets, or the like, and hence the originality of the document cannot be certified.
