Abstract
An image forming apparatus is provided which can properly manage individual information after replacement and history of replacement on the apparatus side. If individual information is successfully read from a toner cartridge storing the individual information, the image forming apparatus records the individual information in an apparatus-side memory. At a predetermined timing of when there is a possibility that the toner cartridge is replaced, the image forming apparatus attempts to read information from the toner cartridge. If the reading fails and the individual information recorded in the apparatus-side storage is not information read from the toner cartridge, the image forming apparatus writes new individual information about the toner cartridge to the apparatus-side storage, and records information generated on the apparatus side in the written individual information.
