Abstract:
1. An image forming apparatus comprising: a generation section which generates time stamp data, an image forming section which forms an image on a sheet based on a synthetic image data which is synthesized of the time stamp data generated by the generation section and an image data of a job, a nonvolatile memory, an electric power switch for turning on and off a power supply, a control section which controls execution of the job of the image forming section and reads out a time stamp of a time of execution of the job from the generation section as time stamp data which is to be synthesized with the image data of the job, wherein, in a case where the control section detects that the electric power switch is turned off while executing the job, the control section interrupts the execution of the job, memorizes the interrupted job including interrupted image data and the time stamp data which were to be synthesized with the interrupted image data in the nonvolatile memory, and turns off the power supply.
