IMAGE FORMING APPARATUS, IMAGE FORMING METHOD, AND COMPUTER-READABLE RECORDING MEDIUM HAVING IMAGE FORMING PROGRAM RECORDED THEREIN

摘要

PROBLEM TO BE SOLVED: To provide an image forming apparatus which certainly reproduces the decolored image even if an image disappears by being erroneously decolored when forming the image with a decolorable colorant.

SOLUTION: The image forming apparatus includes: an image data obtaining unit that obtains image data of an image formed on a sheet; an identification information obtaining unit that obtains identification information that identifies the sheet on which the image is formed; an image forming unit that forms an image based on the image data obtained by the image data obtaining unit on the sheet with a decolorable colorant which becomes colorless by a predetermined chemical reaction and that forms an identification information image based on the identification information on the sheet with a non-decolorable colorant which does not become colorless by the chemical reaction by which the decolorable colorant becomes colorless; and a storage control unit that stores the identification information and the image data of the image to be formed on the sheet, on which the identification information image corresponding to the identification information is formed, in a predetermined storage region in a correlated manner.
