Abstract
A wireless communication apparatus and method in an image-forming system employ RFID tags capable of transmitting/receiving data via wireless communication. The RFID tags are mounted, respectively, on bottoms of fixing and developing units of the image-forming system, or on bottoms of feed and Organic Photosensitive Conductor (OPC) units of the image-forming system in case if the image-forming system has a detachable developing unit structure. An RFID reader is provided as an integral component of the motherboard or mounted as a separate module thereon. Priorities for wireless communication are assigned to the RFID tags mounted on the units and, according to the priorities, the RFID reader performs wireless communication with the RFID tags to read and write data from/into the RFID tags.
