ABSTRACT:
A sheet processor capable of punching a sheet of paper without causing degraded alignment for filing or deteriorated quality of binding, and an image forming apparatus equipped with the sheet processor are provided. The sheet processor includes a punched hole detector for detecting whether a punched hole has already been made at an intended punching position in a sheet of paper on which an image has been formed, and a controller that controls a punching unit so as not to carry out a punching operation if it is determined that a punched hole exists at the intended punching position on the basis of a signal from the punched hole detector.
