Abstract:
An electrophotographic photoreceptor used in an electrophotographic image forming apparatus for forming an image on a recording medium, the electrophotographic photoreceptor comprising:a conductive base; a photosensitive layer formed on the conductive base; a noncontact information medium disposed on the conductive base or photosensitive layer, the noncontact information medium being provided with an antenna part which communicates with main body communication means of a main body of the electrophotographic image forming apparatus in a noncontact state via electromagnetic waves and a control part including a memory which stores management information for managing the electrophotographic photoreceptor and controls the antenna part so as to communicate with the main body communication means; and wherein the noncontact information medium includes a resonance circuit comprising a coil electrically connected to a capacitor, wherein the resonance circuit transmits the electromagnetic saves from the coil to the main body communication means using at least one frequency based at least on a capacitance of the capacitor.
