<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of performing radio communication with each radio tag without need of providing a means for discriminating whether or not a received predetermined a signal is the signal for itself on each radio tag. <P>SOLUTION: In a copying machine 1, a first main body side antenna 181 and a first tag side antenna 21a corresponding to each other, and a second main body side antenna 182 and a second tag side antenna 22a corresponding to each other are respectively set to have antenna characteristic synchronizing with electromagnetic wave in a different frequency band. By properly using the frequency of a transmission signal (that is, information read signal and information write signal) output from a transmission and reception part 17 to an antenna part 18, the radio communication is respectively performed individually between the transmission and reception part 17 and the first radio tag 21 and between the transmission and reception part 17 and the second radio tag 22. <P>COPYRIGHT: (C)2008,JPO&INPIT |
