摘要：
The image forming apparatus includes: a random number information generation part that generates random number information; a first encryption part that encrypts the random number information generated by the random number information generation part with using a first encryption key; a second encryption key generation part that newly generates a second encryption key from the random number information generated by the random number information generation part; a second encryption part that encrypts specific information for identifying the apparatus with using the second encryption key generated by the second encryption key generation part; a code data creation part that creates code data based on encrypted random number information encrypted by the first encryption part and encrypted specific information encrypted by the second encryption part; and an image forming part that forms a code image based on the code data created by the code data creation part on a recording medium.
