Abstract
This invention relates to an improved automatic document feeder which may be used, for example, on an image forming apparatus. The apparatus in accordance with the invention includes a final document detecting circuit which detects whether a document sent from an original setting device onto an original mounting device is the final document of a set. A normal end detecting device detects whether all of the image forming steps have been completed normally as to the final document of the set. A controlling device moves the final document to be discharged outside of the automatic document feeder after all of the image forming steps have been finished normally on the final document. The controlling device is activated based on signals from the final document detecting device and the normal end detecting device. The control circuit allows documents other than the final document to be moved outside of the image forming device before all of the image forming steps have been completed normally.
