Abstract
An image forming system, for preventing forgery of paper money, a check, securities or the like, having a plurality of copying apparatuses, and a controller, for controlling each of the copying apparatuses, connected with them through a communication line. The copying apparatus includes a reader which reads an image as of the paper money, etc. and which outputs image data corresponding to the image; a printer for printing the image read by the reader on paper; a first transmitter for transmitting the image data to the controller through the communication line; and a prohibiting device for prohibiting an operation of the printer. A signal, which prohibits copying, is transmitted from the controller to the copying apparatus. The controller includes a deciding device for deciding whether or not the data received from the copying apparatus corresponds to an image which is prohibited from being copied; and a second transmitter for transmitting the signal which prohibits copying to the copying apparatus through the communication line, if the deciding device decides that the data received from the copying apparatus corresponds to the image which is prohibited from being copied.
