PURPOSE:To simplify service maintenance, to reduce the volume of a toner cartridge and to prevent image quality from being deteriorated by integrating a discharged-toner tank with the toner cartridge. CONSTITUTION:A spiral projection 2 is formed on the inner surface of the hollow cylindrical member 1 of the toner recovery and supply-integrated type toner cartridge A and the member 1 is divided into a toner supply part 4 and a toner recovery part 5 by a partition plate 3. A cover 6 is fitted to the end of the toner supply part 4, and a toner discharge port is provided on the cover 6. The member 1 is rotatably and pivotally supported to a device main body. The partition plate 3 in the member 1 moves toward the toner supply part 4 when the member 1 is rotated, and the capacity of the toner recovery part 5 is increased by as much as the reduction of the toner in the toner supply part 4, so that the recovered toner can be received. |
