When a discharged toner box 3 is detached, discharged toner is prevented from being scattered. A discharged toner collecting apparatus 1 includes a discharged toner box 3 for storing discharged toner, a discharged toner nozzle 4 for injecting discharged toner into the interior of the discharged toner box 3, and a connecting portion 5 to which the nozzle 4 is connected. At the position where the nozzle 4 and the connecting portion 5 are connected, a washing fluid feeding unit 6 for feeding washing water to wash the inner surface of the nozzle 4 is provided. The washing fluid feeding unit 6 is constituted by a washing fluid tank 14 for storing washing water, a washing fluid nozzle 15 for ejecting the washing water to an inner surface of the nozzle 4, and the washing fluid feeding unit 16 for feeding the washing water to the nozzle 15. The nozzle 15 is constituted by a circular pipe portion 18 which surrounds a vertical pipe unit 13, and flow control vanes 19 for guiding the washing water to the interior of the vertical pipe unit 13. The washing water is caused to flow from slits 19A formed between the flow control vanes 19 to the interior thereof in a swirly manner so as to wash the discharged toner adhered on the inner surfaces thereof.

1. A discharged toner collecting method, wherein, in a case where a discharged toner box containing discharged toner stored therein is replaced so as to collect the discharged toner, when a discharged toner nozzle, which is connected to a connecting portion provided at the discharged toner box and adapted to inject discharged toner into the interior of the discharged toner box, is released from the connecting portion, the discharged toner nozzle, or both of the discharged toner nozzle and the connecting portion, are washed by means of washing fluid. 2. The discharged toner collecting method according to claim 1, wherein inner surfaces of the discharged toner nozzle and the connecting portion are cylindrically-shaped, and the washing fluid is caused to flow in a swirly manner along the cylindrically-shaped inner surfaces so as to wash the inner surfaces. 3. The discharged toner collecting method according to claim 2, wherein the washing fluid is a liquid, a gas, or a grain-like material capable of removing discharged toner adhered on the inner surface of the discharged toner nozzle or the connecting portion. 4. The discharged toner collecting method according to claim 1, wherein the washing fluid is a liquid, a gas, or a grain-like material capable of removing discharged toner adhered on the inner surface of the discharged toner nozzle or the connecting portion. 5. A discharged toner collecting apparatus including at least a discharged toner box for storing discharged toner, a discharged toner nozzle for injecting discharged toner into the discharged toner box, and a connecting portion which is provided in the discharged toner box and to which the discharged toner nozzle is connected, wherein there is provided, at a position where the discharged toner nozzle and the connecting portion are connected, a washing fluid feeding mechanism for feeding washing fluid to wash an inner surface of the discharged toner nozzle, or both of inner surfaces of the discharged toner nozzle and the connecting portion. 6. The discharged toner collecting apparatus according to claim 5, wherein the washing fluid feeding mechanism comprises a washing fluid tank for storing washing fluid, a washing fluid nozzle for ejecting the washing fluid stored in the washing fluid tank to inner surfaces of the discharged toner nozzle, or both of inner surfaces of the discharged toner nozzle and the connecting portion, and a washing fluid feeding unit for feeding washing fluid stored in the washing fluid tank to the washing fluid nozzle. 7. The discharged toner collecting apparatus according to claim 6, wherein the washing fluid nozzle comprises a circular pipe portion which is provided at an upper portion of the discharged toner nozzle and surrounds the discharged toner nozzle, and flow control vanes which constitute an inside wall provided inside the circular pipe portion and guides washing fluid flowing inside the circular pipe portion to the discharged toner nozzle. 8. The discharged toner collecting apparatus according to claim 6, wherein the discharged toner nozzle is formed in the shape of a cylindrical pipe; and the washing fluid nozzle comprises a circular pipe portion which is provided at an upper portion of the discharged toner nozzle and surrounds the discharged toner nozzle, and one or more flow control vanes which constitute an inside wall provided inside the circular pipe portion and guide the washing fluid flowing inside the circular pipe portion to the discharged toner nozzle so as to cause the washing fluid to flow in a swirly manner.
