A copying apparatus detects as to whether or not an IC chip is present in an original paper. When the IC chip is detected, the copying apparatus reads data from this IC chip. When the read data is additional information, which can be printed as an image, the copying apparatus stops a printing process, and notifies a message indicating that the read data is the additional information to the user and then, waits for an instruction issued by the user. When the user instructs to print the additional information, the copying apparatus prints the image read from the original paper and the additional information read from the IC chip on a printing paper in an output format designated by the user.
