Description
【発明の詳細な説明】 本発明は現像剤貯蔵容器に関するものである。[Detailed description of the invention] The present invention relates to a developer storage container.
従来電子写真装置、特に粉体の現像剤を用いる乾式の装

される。Conventionally, in electrophotographic devices, especially dry type devices that use powdered developer, various methods have been proposed to prevent the developer (hereinafter referred to as toner) from scattering when replenishing the developer, such as placing the toner in a cartridge. It has also been put into practical use. However, it is difficult to completely prevent toner scattering. Furthermore, since it is not possible to identify the user of a copying machine intended for personal use, it is required to completely prevent scattering.
そこでパーソナルユースの機械で社、感光ドラム、現像

点で上記ユニットが一体となったキットを交換し、使い
終ったキットは捨ててしまう事が考えられる。Therefore, in a machine for personal use, the printer, photosensitive drum, developer, cleaner, and charger are integrated, and when the specified number of sheets is reached, the kit containing the above units is replaced, and the kit that is used is discarded. is possible.
熱論製造者が回収して再使用する事も可能である。It is also possible for the thermal theory manufacturer to collect and reuse it.

に優れた装置を提供することができる。With K in this way, it is no longer necessary to attach and detach the developing device body and the cartridge, which not only prevents scattering, but also allows the user to simply replace the kit, instead of replacing the photosensitive drum, replenishing toner, and disposing of waste toner as in the past. Since there is no need to individually perform complicated operations such as cleaning the charging wire, it is possible to provide an apparatus with very excellent operability.
しかしながら現像器本体において、マグネットスリーブ

することは非常に困難であり、またキットとして考えた
場合、トナーの防湿の為キット全体を密閉した容器へ入
れておかねばならず、好ましくない。However, it is very difficult to completely prevent toner from scattering from the gap between the magnetic sleeve and the housing in the developing unit, and when considering a kit, the entire kit must be placed in a sealed container to prevent the toner from moisture. It has to be kept in there, which is not desirable.

外部よりシールを取り去る事により、トナーの飛散を防
止し、かつトナーの防湿対策も兼ねる事を目的とする。The present invention involves dividing the inside of the developing device, sealing the toner in a space sealed with a sealing material, and removing the seal from the outside of the developing device after setting the above-mentioned kit including the developing device as a unit in the main body of the device. The purpose is to prevent the toner from scattering and also serve as a moisture-proofing measure for the toner.
これによればトナー収納部を別部品とし、組立時最後に
トナー収納部を組みつけることができるようになるので
組立性の向上を図ることも可能となる。According to this, the toner accommodating section can be made as a separate component and the toner accommodating section can be assembled at the end of assembly, so that it is also possible to improve the ease of assembly.
