ABSTRACT:
An image forming apparatus has a plurality of detachably loadable replacement units. The replacement units each have an individual IC tag that performs data writing or reading through non-contact wireless communication. At least one reader/writer writes/reads data to/from the IC tags of the replacement units through non-contact wireless communications. A shield member defines a shielded area in the image forming apparatus for shielding electromagnetic radiation noise. At least the IC tags and an antenna part of the reader/writer are arranged in shielded area.
