The image output unit outputs an image. The nonvolatile storage unit stores information even in the event of a power interruption. The original-image generating device generates an original image in the nonvolatile storage unit. The log-image generating device generates a log image based on the original image. Further, when the image forming apparatus is started, if the original image is stored in the nonvolatile storage unit, the log-image generating device generates the log image based on the original image stored in the nonvolatile storage unit. ## Claims ### Claim 1 An image forming apparatus comprising: an image output unit configured to output an image;
