An image reading apparatus includes an RFID (radio frequency identification) detection unit that detects a reading RFID (radio frequency identification) tag disposed to a reading target; an image reading unit that reads an image of the reading target; a diagnosing RFID (radio frequency identification) tag capable of being detected by the RFID detection unit; and an abnormality determination unit that determines abnormality based on a state of detection of the RFID detection unit. When the diagnosing RFID tag is detected at the time the reading RFID tag is not detected by the RFID detection unit, the abnormality determination unit determines abnormality of the reading RFID tag, and when the diagnosing RFID tag is not detected, the abnormality determination unit determines abnormality of the RFID detection unit.
