An image forming apparatus includes a forming device, a wireless tag communication device, an external communication interface, and a processor. The forming device forms an image on a sheet including a wireless tag. The wireless tag communication device performs wireless communication with the wireless tag included in the sheet. The external communication interface acquires an image forming data file from another device through communication. The processor forms the image on the sheet by controlling the forming device based on information included in the image forming data file if the image forming data file includes an instruction for image formation, and sets parameters of the wireless tag communication device based on information included in the image forming data file if the image forming data file includes an instruction for wireless tag communication setting.
