Abstract
A postprocessing device includes a pair of folding rollers, a folding blade, a transport device, a roller driver, a blade driver, and a drive controller. The drive controller selectively performs one of a first rotation control, including controlling the roller driver to keep rotation speed of the pair of folding rollers constant, while the folding blade is moving away from a nip region, and a second rotation control, including controlling the roller driver to stop the rotation or slow down the rotation speed of the pair of folding rollers, while a tip portion of the folding blade is being withdrawn from a folded portion of a sheaf of sheets folded, and to restore the rotation speed of the pair of folding rollers to original rotation speed, after the tip portion of the folding blade has been removed from the folded portion of the sheaf of sheets folded.
