Abstract

When an operator starts an operation for copying in full-color image forming mode, a predetermined warning to copy-protected materials and others is given to the operator, and an actual copy cannot be performed unless the operator confirms this warning. When the operator starts the operation of copying in the full-color image forming mode, and/or during the copying operation, a third party such as a manager of the copying machine is notified of these facts for enabling help in the copying operation and finding the copying of copy-protected materials.
