PROBLEM TO BE SOLVED: To improve operability by reducing waiting time at the time of turning on a power source. SOLUTION: This copying machine, which executes the self-diagnostic processing of the copying machine itself by turning off the power source of own machine in the case that it is not operated for specified time, is provided with a nonvolatile storage part 204 to store the result of the self-diagnostic processing and a CPU 201 executing the execution control of the self-diagnostic processing based on the result of the self-diagnostic processing before turning off the power source stored in the nonvolatile storing part 204 when the power source of the copying machine is turned on by executing the self-diagnostic processing before turning off the power source and storing the result of the self-diagnostic processing before turning off the power source at the nonvolatile storage part 204. |
