Abstract

An image forming apparatus including a condition determining device for determining optimum conditions automatically for copying a document during copying, a blank lamp for recording information concerning the determined conditions in code on a sheet of copy paper, a code scanner for reading the coded information when producing a copy from the copy paper carrying the code thereon, and control circuits for setting copying conditions according to the read information. With this configuration, when producing copies of the image on the original document, by reading the coded information and setting the copying conditions, an image satisfying the optimum conditions is readily obtained whenever it is desired. Moreover, even when making copies from a copied image which was produced through subsequent copying, the formed images always have the same quality that the original has.
