 A copying machine according to the present invention having a multi-job function can perform processing to a current job and a sub job, and errors are divided into two stages. If a high level error occurs in a job processed as the sub job, the job is switched to the current job, and the error is widely displayed on the entire display portion. If a low level error occurs in a job processed as the sub job, the error is displayed in a small sub job display portion in the display. As a result, the user can be accurately informed of an error occurring in the sub job in the copying machine.
