Abstract: There is a need to provide an image generator and an image generation method capable of avoiding wasting a normal printed matter if any in sheets of paper output after an occurrence of waste paper.

Detection of the waste paper allows an image generator to perform reprint from a print job for the waste paper. Normal-image paper may be contained in sheets of paper output between detection of the waste paper and the reprint to be performed. In this case, the normal-image paper is used as a normal printed matter and is avoided from being consumed wastefully.
