Image forming apparatus

An image forming apparatus, comprising:

• an image forming device configured to form an arbitrary image on a medium having a target wireless tag, which is a wireless tag that is a data writing target;
• a wireless tag communication device that is arranged at a predetermined position with respect to the image forming device and configured to communicate with the target wireless tag of the medium, and write data to the target wireless tag and read data written to the target wireless tag;
• and
• a processor configured to
• preceding writing of arbitrary data to the target wireless tag by the wireless tag communication device, read data prestored in the target wireless tag by the wireless tag communication device and perform recognition processing for recognizing the target wireless tag on a basis of the read data,
• in a case where the recognition processing for the target wireless tag has failed, perform at least one of stepwisely decreasing a reception threshold of radio signal strength to be returned from the target wireless tag or stepwisely increasing radio signal strength to be transmitted to the target wireless tag, read data prestored by the wireless tag communication device, and perform re-recognition processing for recognizing the target wireless tag on a basis of the read data, and
• notify a user that the medium having the target wireless tag recognized in the re-recognition processing is a re-recognized medium whose target wireless tag has been recognized in the re-recognition processing.
