ABSTRACT:
A bookbinding device includes a collecting device for collecting sheets into a bundle and a bookbinding path that includes a sheet bundle conveying device, an adhesive applying device, a cover binding device, and a cover sheet feeding path. The cover binding device includes a back folding press member for the cover sheet and a back rest plate member to back up the cover sheet. A control device allows the back folding press member to execute a back folding process with a small gap formed between the back rest plate member and a back of the sheet bundle. The control device further allows the back of the sheet bundle to abut against the back rest plate member to forcibly cool the adhesive. The control device varies the time required for the cooling depending on the thickness of the sheet bundle.
