Image forming apparatus configured to modify a bookbinding operation based on a maximum number of bindable sheets, image forming method, computer program product, and storage medium having recorded the computer program product configured to perform same

An image forming method, comprising the steps of:

• detecting, via a processor included in a controller, a number of manuscript sheets on which an image is formed;
• calculating, via the processor, an anticipated number of sheets of recording media on which the image is to be formed based on a print job associated with printing the image, the print job including the detected number of sheets and an additional sheet as a cover arranged on an outside of multiple recording media which are stacked in an overlapping manner;
• determining, via the processor, whether the anticipated number of sheets calculated exceeds a set number of sheets;
• and
• instructing, via the processor, a bookbinding device to bind the multiple recording media by omitting the cover on the outside of the multiple recording media when performing post-processing on the print job, if the anticipated number of sheets exceeds the set number of sheets.

A non-transitory computer readable recording medium comprising instructions that, when executed by a processor included in a controller of an image forming apparatus, configures the processor to,

• detect a number of manuscript sheets on which an image is formed,
• calculate an anticipated number of sheets of recording media on which the image is to be formed based on a print job associated with printing the image, the print job including the detected number of sheets and an additional sheet as a cover arranged on an outside of multiple recording media which are stacked in an overlapping manner,
• determine whether the anticipated number of sheets calculated exceeds a set number of sheets, and
• instruct a bookbinding device to bind the multiple recording media by omitting the cover on the outside of the multiple recording media when performing post-processing on the print job, if the anticipated number of sheets exceeds the set number of sheets.
