Patent ID: 7177556

Claim:
An image formation device that uses recording agents of multiple colors to form a color image on a medium like paper, said image formation device comprising: an image formation module that holds multiple recording agent cartridges respectively filled with the recording agents of the multiple colors in an attachable and detachable manner and integrally moves said multiple recording agent cartridges in a circumferential direction to sequentially form corresponding color component images and to eventually form a color image with supplies of the recording agents from said multiple recording agent cartridges; an information transmission module that is arranged at a specific location facing a preset posterior circumferential position where each of the multiple recording agent cartridges reaches after formation of a corresponding color component image at an image-forming circumferential position, said information transmission module transmitting information regarding cumulative consumption of recording agents with the additional consumption of the recording agents during formation of a corresponding color component image in a contactless, storable manner to a storage element mounted on a certain recording agent cartridge, which has just completed formation of a corresponding color component image at the image-forming circumferential position and has moved in the circumferential direction to the posterior circumferential position; and a control module that controls said information transmission module to store image formation-relating information, which regards formation of the color image by said image formation module, into each of said storage elements mounted on said multiple recording agent cartridges.
