Problems solved by technology

[0006] However, in Japanese Patent Laid-Open No. 2000-214667, there is also a problem that if the toner cartridge is left for a long time with the toner outlet facing down, the fluidity of the toner will be lost (if it becomes a slowly coagulated state) Therefore, when the auger screw is rotated during the initial toner replenishment operation after being installed in the image forming apparatus, the toner near the toner discharge port cannot be discharged out of the toner cartridge. As a result, there is no The removed toner is compressed into clumps due to the pressure of the auger screw, whose rotation is locked

Abstract

A toner cartridge includes a container (140) for containing toner, a toner discharge section (141) having a toner discharge port (141a), an auger screw (142) provided in the container (140), for conveying toner in the container (140) to the toner discharge section (141), a shutter (144) for opening and closing the toner discharge port (141a), and a toner flowing-out preventing member (143) provided in a communicating part between the container (140) and the toner discharge section (141), for preventing flowing out of toner by closing an opening of the communicating part. The toner flowing-outpreventing member (143) is configured so as to open the opening in conjunction with an opening operation of the shutter (144).

Description

technical field [0001] The present invention relates to toner cartridges used in image forming apparatuses such as laser beam printers and multifunction machines, and more particularly to toner hoppers, toner bottles, etc. A toner cartridge and an image forming apparatus using the same. Background technique [0002] Conventionally, an electrophotographic image forming apparatus, such as a copying apparatus, a facsimile apparatus, a printer, or a multifunctional machine equipped with these functions, using a two-component developer is configured such that a toner replenishing apparatus such as a toner cartridge is used to supply Automatic supply of toner for continuous operation of image output. Furthermore, when the toner is used up, the toner can be easily replenished by exchanging the toner cartridge, the process cartridge, or the like. [0003] When toner containers such as toner cartridges and process cartridges are stored in warehouses or the like, there are cases whe...
