Abstract:
1. An image forming apparatus comprising: an exposure section to form an electrostatic latent image on a photosensitive body on the basis of image data and light quantity correction data, the exposure section including a plurality of LED elements; an RFID tag provided in the exposure section, the RFID tag including a light quantity correction data storing section to store the light quantity correction data for adjusting light quantities of the LED elements, and a communication section to perform wireless communication; an RFID reader/writer to perform the wireless communication with the RFID tag; a reading control section to make the RFID reader/writer perform the wireless communication with the RFID tag so as to read the light quantity correction data from the light quantity correction data storing section of the RFID tag during a period when no processing related to the image data is performed; a storage section to store the light quantity correction data read by the reading control section from the light quantity correction data storing section of the RFID tag; and a writing control section to transmit light quantity correction data to be written to the RFID tag by making the RFID reader/writer perform the wireless communication with the RFID tag during the period when no processing related to the image data is performed when receiving a writing instruction of the light quantity correction data from an external apparatus through an operation section or through an external I/F provided in the image forming apparatus, and to rewrite the stored light quantity correction data in the light quantity correction data storing section of the RFID tag into the transmitted light quantity correction data so as to update the data.
