PROBLEM TO BE SOLVED: To perform enclosure and sealing by automatically increasing the number of repetition times of folding after the second booklet when the enclosure and sealing of a folding-processed booklet is not performed normally.SOLUTION: When the inspection result of a flap of an envelope is determined to be abnormal, the envelope is ejected onto an abnormal ejection tray of an envelope inspection device (S108). After the number of repetition times of folding necessary for enclosing in the envelope is determined from the number, type, and thickness of the sheets of the contents in the envelope (S109), a recovery processing is performed. The prepared saddle stitch booklet is repeatedly folded the number of times determined in S109 (S112), and the saddle stitch booklet is enclosed in the envelope and sealed (S113). Then, the flap of the envelope is inspected (S114). When the flap is determined to be normal (S114: OK), the envelope is ejected onto a normal ejection tray 6 (S115), When the flap is determined to be abnormal (S114: NO), an error display is performed on an operation panel of an image forming device (S116), and the envelope determined to be abnormal is ejected onto the abnormal ejection tray (S117).
