Abstract
A device for and method of managing status information on a consumable for an image forming device by using memory included in the consumable is provided. The image forming device having more than one consumables and transferring an electrostatic image formed on a surface of a photosensitive medium onto paper comprises an image forming unit printing a predetermined image in response to a control of a central controller, and a management memory storing management information related to status information of the consumables. The central controller reads the consumable information including remaining lifetime of the consumable from a consumable memory including in the consumable, reads the management information from the management memory included in the image forming device, calculates an amount of use of the consumables during an operation of the image forming device, and updates the consumable information and the management information using the calculated amount of use.
