PROBLEM TO BE SOLVED: To provide a paper post-processing device which is installed in an image forming device, which is reduced in size and cost, and which can secure conveying performance irrespective of the type of paper. SOLUTION: This paper post-processing device includes a first conveying path for guiding sheets to be conveyed into a first post-process unit, a conveyance standby path which comprises a first standby path branched from the branch point of the first conveying path and a second standby path which is formed continuously with the first standby path and converged on the first conveying path and which waits for the sheet conveyed to the first post-process unit through the first standby path and the second standby path, a second conveying path which is branched from the branch point of the first standby path and which guides the sheets conveyed into the first standby path to the second post-process unit, a first path changeover means which is installed at the branch point of the first conveying path and which changes over and connects the first conveying path to the first standby path or the first post-process unit side, and a second path changeover device which is installed at the branch point of the first standby path and which changes over and connects the first standby path to the second standby path or the second conveying path.
