The image forming apparatus is various in form, such as a printer, a copying machine, a scanner, and the like. An image forming consumable, such as an ink cartridge, a powder cartridge, or the like, in which a developer for image formation is loaded, and an image forming main body forms an image on a medium such as paper using the image forming consumable. The imaging consumables are generally fixedly provided with a memory chip, which can be called consumable chip. The imaging consumable chip generally comprises a storage unit and a communication interface unit, wherein the storage unit records not only relevant information of the imaging consumable, such as model, color, total amount of developer and other initialization information, but also printing date, residual amount of developer, printing information and the like in the printing process. The imaging main body reads and writes the consumable chip through the communication interface unit.
As miniaturization of the image forming apparatus progresses, the volume of consumables mounted on the image forming apparatus also becomes smaller and smaller, and thus the chip mounting on the powder cartridge or the ink cartridge is often restricted by the mounting position.
