Abstract
An image forming apparatus stores an ID number input through an auditor in a memory section when a paper money judging section judges that image data obtained from an image reading section is the image data of paper money. With this structure, the fact that an attempt to perform counterfeiting was made is known by reading out the ID number stored in the memory section. In this case, since it is understood that a counterfeiter knew a specific ID number, the counterfeiter can be detected from a limited number of people. It is thus possible to take some measures to prevent recurrence of counterfeiting by, for example, enhancing the inspection of the image forming apparatus and giving a warning to the counterfeiter.
