Abstract
Abstract An image forming apparatus equipped with a binding function includes an image forming unit for forming an image onto a sheet, a binding unit provided adjacent to the image forming unit, and a malfunction detector for detecting malfunction in the operation of the binding unit. The binding unit is provided with a binding condition display, and the image forming unit is provided with an alphanumeric character display and a device for instructing the start of an image forming operation. A detected malfunction is indicated by at least one of these displays. Upon detection of a malfunction by the malfunction detector, operation of the binding unit stops, or the entire operation of the apparatus stops.
