Zusammenfassung:	A copy machine achieves a reduction in power consumption when performing a saddle-stitching operation. An image forming unit forms visible images on recording sheets in accordance with image data stored in a memory device. A post-processing unit collects the recording media on an individual copy basis to prepare a bundle of the recording sheets, and performs a saddle-stitching process and a center-folding process on the bundle of the recording sheets. The post-processing unit ejects the processed recording sheets onto a predetermined eject tray. A system control part determines whether or not a total number of the recording sheets corresponding to the image data is within a limit number for the saddle-stitching process. When the total number of the recording sheets exceeds the limit number for the saddle-stitching process, the recording sheets are ejected onto the at least one eject tray other than a predetermined eject tray.
