A method and apparatus for efficiently scanning a duplex document in which a scan unit sequentially scans both sides of a sheet of a duplex document by moving the sheet across a reader, and a reverse output unit to output the sheet after turning over the sheet. Therefore, since the sheet of a document can be fed and scanned while the second side of the previous sheet of the document is scanned, scanning time can be reduced. Particularly, the reduction in scanning time is very useful when multiple sheets of a duplex document need to be scanned.

An image reading apparatus for use in an image forming apparatus includes a document glass installed on an upper side of the image reading body on which a document is placed; an image reading sensor installed under the document glass for stopping after being transferred to a predetermined position or for reciprocating in a straight direction parallel to the document glass; a cover for opening and closing the upper surface of the document glass; an automatic document feeder (ADF) for feeding the document to the position to which the image reading sensor is fixed; a document discharging plate for discharging the document fed through the automatic document feeding unit; first and second guide members for guiding to allow the document fed through the automatic document feeding unit to be discharged to the document discharging plate, the first and second guide members being installed at a predetermined interval to expose the document toward the image reading sensor; and a guide film installed to cover the interval between the first and second guide members for guiding to allow the document to be discharged to the document discharging plate. By this structure, a size of the image forming apparatus can be reduced.

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.
