An enclosing apparatus for enclosing an enclosure into an envelope at an enclosing position includes a conveyance roller that conveys the envelope to the enclosing position and an envelope conveyance path through which the envelope is conveyed. An enclosing support is disposed in the envelope conveyance path and supports enclosing of the enclosure into the envelope. The enclosing support retracts a flap of the envelope from the envelope conveyance path while the conveyance roller conveys the envelope to the enclosing position.

To prevent displacement of first fold positions and collapse of discharged and stacked sheets when sheet fold processing is performed a plurality of times for each sheet. First fold processing is applied to a sheet conveyed to a conveying path by a rotating body pair 22. The sheet that has been subjected to the first fold processing is fed back to the conveying path while a first fold line is being opened. Then, second fold processing is applied to the sheet that has been fed back to the conveying path by the rotating body pair 22. The resultant sheet is discharged with the first fold line opened.
