Claim 0:
1. A post-processing apparatus comprising:
a buffer unit that includes:
a first transport path that transports sheets, which are sent from an image forming unit, in a downstream direction of the first transport path; and
a second transport path that branches off from the first transport path, the second transport path being capable of temporarily holding at least one of the sheets that comes out of the first transport path by being reversed and transported opposite to the downstream direction of the first transport path, wherein
the buffer unit sequentially transports the sheets from a position below an uppermost edge of a first sheet temporarily held in the second transport path such that a second sheet becomes stacked with the first sheet and the two sheets are transported to the first transport path and the second transport path while being stacked on top of one another; and

a compilation tray that is inclined relative to a vertical line passing through the second transport path such that the sheets supplied from the second transport path are transported into the compilation tray from above the compilation tray, intersect the compilation tray below a top-most edge of the compilation tray, and are stacked onto a placement surface as a stack of sheets, wherein the compilation tray is in a downstream direction of the second transport path and below the second transport path, and the sheets are placed in order onto the placement surface.
