PROBLEM TO BE SOLVED: To prevent deformation in a vicinity of a crimp part of a paper bundle in which crimp binding is performed, and prevent a paper from being jammed in paper conveyance and being caught when loading.SOLUTION: The paper post-processing device includes: an upper pressing form 210; and a lower pressing form 220, respectively including crimp tooth rows 211 and 221, and puts the paper bundle P between the pressing forms 210 and 220 and compresses it to perform crimp binding processing of the paper bundle P. Pressing members 212 and 222 formed of an elastic body, in which a part adjacent to a crimp part of the paper bundle P is put between them to be fixed in crimp binding processing, are arranged on both pressing forms 210 and 220. Thus, a periphery of the crimp binding part of the paper bundle P is pressed in the crimp binding processing, and deformation of the paper bundle P is prevented. |
