ABSTRACT:
An image forming apparatus and an IC card are provided with a function of transmitting a signal with no contact with each other in a signal receivable range in order to prevent copying aggregation from being omitted due to forgetting to insert the IC card and to prevent the IC card from being left attached after a copying operation is completed. The image forming apparatus is brought into a condition where an image forming operation can be performed by receiving a signal from the IC card which is brought into the signal receivable range.
