TONER CARTRIDGE ASSEMBLY AND IMAGE FORMING SYSTEM

摘要

PURPOSE: A toner cartridge assembly and an image forming system are provided to improve a toner cartridge assembly to maintain a developing nip uniform and to reduce the quantity of abrasion due to mechanical contact of a photosensitive drum and a developing roller. CONSTITUTION: A toner cartridge assembly includes a new toner cartridge(310) and a waste toner cartridge(330). The new toner cartridge is set in the main body(100) of an image forming system, corresponding to a photosensitive drum cartridge(200), and has a developing roller that provides a new toner stored in the cartridge to the photosensitive drum. The waste toner cartridge is movably combined with one side of the new toner cartridge and stores waste toner collected from the photosensitive drum cartridge. The new toner cartridge is relatively moved with respect to the waste toner cartridge to control a developing nip between the developing roller and the photosensitive drum.
