In order to prevent a sheet of paper on which confidential information is formed as an image from being taken out, an MFP has a print data accepting portion to accept print data, an image-forming portion to form an image based on the print data onto a sheet of paper having an RFID tag provided with a memory and a data communication portion, an RFID reader/writer control portion to acquire tag identification information for identifying the RFID tag provided by the sheet of paper on which the image is formed based on the print data, a definition data control portion to store definition data including the acquired tag identification information, an external reader communication portion to communicate with a communicable RFID reader, and an abnormal state detecting portion to judge as an abnormal state the case where the external reader communication portion communicating with a communicable RFID reader is detected to be non-communicable with the RFID tag specified by the tag identification information included in the definition data.
