Special-document discriminating apparatus and managing system for image forming apparatus having a special-document discriminating function

A managing system for an image forming apparatus comprising an image forming apparatus and a managing apparatus placed at a position remote from the image forming apparatus and connected with the image forming apparatus via a communication line, said image forming apparatus comprising:

• detecting means for detecting features of a predetermined special-document from image data of an original;
• determining means for determining whether or not the original corresponds to the predetermined special document in accordance with the detection result obtained by the detecting means;
• sending means for sending, when the original is determined to correspond to the predetermined special-document by the determining means, determination result information to an external unit;
• wherein said image forming apparatus further comprises adding means for adding additional information associated with image forming operation to said determination result information;
• and
• wherein said managing apparatus comprises means for sending to said image forming apparatus an operation prohibiting signal for prohibiting operation of said image forming apparatus in accordance with said determination result information, and a cancellation signal for canceling the prohibition of the operation.
