<p>PROBLEM TO BE SOLVED: To prevent storage processing from adversely influencing the other operations even if log information generated by a plurality of log generation means, respectively is written to and stored in nonvolatile storage means.SOLUTION: In a case of writing and storing log information generated by a plurality of log generation means, respectively to and in nonvolatile storage means, the number of stored logs indicating the number of log means used to write the log information generated by the log generation means to the nonvolatile storage means is determined in response to a device operating state (S3, S7 to S10). For example, preferential storage information indicating the log generation means whose log information should be preferentially stored in every device operation state is set, and the log generation means indicated by the preferential storage information corresponding to the device operating state is preferentially selected (S8).</p> |
