Abstract

PURPOSE:To prevent a toner from being leaked to the outside in case of inserting a cartridge, and to prevent the circumference of a device from being stained by the toner by providing an air discharge port on the circumferential wall of a toner cartridge inserting part, and covering the port with a filter. CONSTITUTION:The air discharge port 10 is provided on the housing 9 of the back face side of a cartridge inserting part 8 for replenishing a toner of the upper part of a toner storage part 6, and the discharge port 10 is covered with the filter 11. Accordingly, when the toner cartridge 7 is inserted into the direction as indicated with an arrow (a), air in the inserting part is pushed out and discharged through the filter 11 from the discharge port 10, therefore, no toner is leaked to the back face side of the inserting part. Also, when inserting said cartridge, air is not compressed, therefore, the toner is not leaked from the inlet side. Therefore, when inserting the cartridge, the leakage of the toner is prevented, and the staining of the circumference of a device by the toner is prevented.

The present invention will be explained in detail using the drawings. First, as shown in FIG. 3, the toner supply device of the present invention has a toner storage section (6) for supplying toner into a developing device (not shown).
) is provided at the bottom, and a cartridge insertion section (8) for inserting a toner cartridge (7) for replenishing toner into the toner storage section (6) is provided at the top. An air outlet OQ is provided in the housing (9) on the back side of the cartridge insertion part (8), and in order to prevent toner from leaking to the outside when the toner cartridge is inserted, the air outlet 01 is opened with a filter 0υ. It is made by coating. The filter 00 is made of a material that is fixed using a cage, double-sided tape, or the like.

従来の装置周辺のトナー汚染を解消することができる。As shown in FIG. 3, in the toner supply device of the present invention, when the toner cartridge (7) is inserted from the cartridge insertion port in the direction of arrow a, the air inside the cartridge insertion portion is pushed out and However, due to the action of filter all, the toner does not leak to the back side. Further, since the air inside the cartridge insertion portion is not compressed by the air being discharged, there is no toner leakage from the cartridge insertion port. Therefore, it is possible to eliminate toner contamination around the conventional device that occurs when the toner cartridge is inserted.

。Since the present invention has the above configuration, even when a toner cartridge is inserted from the cartridge insertion port to replenish toner, only the air inside the cartridge insertion port is removed.
The toner is discharged from the air outlet, and there is no possibility that the toner will leak outside. Therefore, it is possible to prevent the problem of contamination of the area around the device with toner every time the car upholstery is replaced, unlike the conventional method, and the practical effects of the present invention are extremely large.
