1. An image forming apparatus comprising:
a wireless tag communication device configured to transmit a radio wave to communicate with a wireless tag, and receive a response wave therefrom;
an image forming mechanism including a transfer roller and configured to form an image on a medium and transfer the image from the medium to a sheet through the transfer roller, according to a control value; and
a controller configured to:
receive a print job for printing an image on a sheet and performing tag processing on a wireless tag embedded in or attached to the sheet,
control the wireless tag communication device to perform the tag processing on the wireless tag,
determine whether the tag processing has completed properly,
upon determining that the tag processing has completed properly, control the image forming mechanism to form the image on the medium and transfer the image from the medium to the sheet according to a first control value, and
upon determining that the tag processing has not completed properly, control the image forming mechanism to form the image on the medium and transfer the image from the medium to the sheet according to at least one second control value different from the first control value, wherein
the first control value indicates a first bias voltage applied to the transfer roller, and
the second control value indicates a second bias voltage applied to the transfer roller and different from the first bias voltage.
