Abstract
When an apparatus is turned on, one developer is positioned to a reading/writing position and a specific area of a cartridge memory is read to judge whether or not an improper detachment flag is set. Unless the improper detachment flag is set, the improper detachment flag is set in the specific area of the cartridge memory after information on life saved in the cartridge memory is read and written in a main-body memory.
