Abstract
A toner cartridge includes a container defining a central axis and a toner-guiding member. The container is provided at one end thereof with an opening having a radius. The toner-guiding member is provided with an annular connecting portion connected with the container, an outlet at one end thereof, a longitudinally-extending portion at the other end thereof extending into the container through the opening, an inlet formed on the longitudinally-extending portion, and a flexible scraping piece mounted on the longitudinally-extending portion and adjacent to the inlet. The scraping piece has a distal end defining with the central axis a distance longer than the radius of the opening, such that the toner in the container can be substantially fully discharged out of the toner cartridge so as to lower the residual quantity of toner in the toner cartridge.
