a stacker for loading thereon the recording sheets on which the images have been formed;
a stapler for conducting a stapling process on the recording sheets loaded on the stacker;
an ejector for ejecting the recording sheets; and
a controller which, when the cancellation of job instruction for a job which includes the stapling process is input via the operation unit and when a number of the recording sheets loaded on the stacker is greater than a preset number, executes a stapling ejection mode in which the recording sheets are subjected to the stapling process by the stapler and then ejected by the ejector.
