Abstract
An image forming apparatus includes a control unit and a storage section. The control unit includes a processor, and through execution of a control program by the processor, functions as a failure information generation section, an information encoding section, and a code generation section. The failure information generation section, upon occurrence of a predefined abnormality related to operation of the image forming apparatus, generates failure information in which information related to the abnormality is visualized in a character. The information encoding section generates encoded failure information obtained by encoding the failure information generated by the failure information generation section. The code generation section generates a code image obtained by one-dimensionally or two-dimensionally coding the encoded failure information generated by the information encoding section. The storage section stores, as an image file, the code image generated by the code generation section.
