The apparatus of the present invention includes memory devices provided in the consumables for writing and reading data related to the consumables and for managing the consumables. As such the present invention uses less signal lines for a development cartridge, informs a user to refill the consumables, and is less sensitive to noise due to the digital management of consumables.
