Image forming apparatus, method of acquiring toner-cartridge information and toner cartridge

摘要

An image forming apparatus of the invention permits a toner cartridge equipped with a non-volatile memory storing various information items to be mounted in a mounting portion of an apparatus main body through a toner-cartridge mounting panel capable of being opened and closed without suspending an image forming operation. In a case where an opened/closed status of the toner-cartridge mounting panel is detected, the apparatus retrieves cartridge-specific information from the non-volatile memory of the toner cartridge. The other data than the cartridge-specific information is read out only from a non-volatile memory of a toner cartridge, the cartridge-specific information of which differs from cartridge-specific information stored in a memory of the apparatus main body.
