クリユーである。 FIG. 1 is a conceptual diagram of a conventional developer powder replenishing device. In the figure, 1 is a plastic container in which developer powder is sealed, 2 is a developer powder replenishment port to which the plastic container 1 is attached and the developer powder is replenished, and 3 is a developer powder supply port replenished from the developer powder replenishment port 2 in the depth direction. It is a rotating screw that transports the

像粉を回転スクリユー３により奥行き方向に搬送
する方法が採られている。 Conventionally, as a developer powder replenishment device for a developing device used in a printing device such as an electrophotographic device, a plastic container 1 is attached upside down to a developer powder replenishment port 2 and developer powder is put in, as shown in the figure. A method is adopted in which the developing powder near the opening 2 is conveyed in the depth direction by a rotating screw 3.

してしまうという欠点を有していた。 However, in such a conventional device, since the developer powder is replenished while being conveyed in the depth direction by the rotary screw 3, it takes a certain amount of time to feed the developer powder uniformly in the depth direction. The plastic container 1 tends to accumulate near the replenishment port 2, making it impossible to replenish uniformly in the depth direction, making it impossible to obtain a constant development quality. This has the disadvantage that the developer powder remaining inside the developer powder overflows around the developer powder replenishment port 2, stains the housing, or adheres to the hands or clothes of the maintenance personnel.

とにある。 The purpose of this invention is to eliminate the above-mentioned drawbacks, that is, to shorten the rise time when replenishing developer powder, to replenish the developer powder uniformly in the depth direction, and to replenish the remaining developer powder in the plastic container. The purpose is to improve the operability of replenishing developer powder without scattering it around the mouth.

ール１４上に均一に補給される。 Next, the operation of the present invention will be explained. The method of replenishing the developer powder 5 to the developing device according to the present invention is to first remove the lid 11 of the cartridge 4 and remove the sealing material 9 with the developer powder discharge opening 7 of the container 6 facing upward. Next, the container 6 is positioned in the insertion port 19 in the above state. Here, insert the notch groove (not shown) in the ring 10 of the cartridge 4 into the housing 1.
3, and insert the container 6 into the housing 13 along the guide plate 15 using the grip 12. After inserting container 6,
The developer powder 5 is uniformly replenished onto the developer powder supply roll 14 by inverting the container 6 with a grip and directing the developer powder discharge opening 7 downward.
このとき袋８は図に示すように挿入口１８にて
蛇腹状を呈する。次に現像粉５投入後、上記操作
の逆操作を行い、容器６を袋８に収納し、筐体よ
り取り去る。 At this time, the bag 8 assumes a bellows shape at the insertion opening 18 as shown in the figure. Next, after charging the developing powder 5, the above operation is performed in reverse, the container 6 is placed in the bag 8, and the container 6 is removed from the housing.
従つて、容器６は現像粉吐出用開口部７を上方
に向けた状態で袋８内に収納されるため、容器６
内に残留する現像粉および容器６に付着している
現像粉を挿入口１９付近に溢することなく筐体１
３より取り去ることができる。 Therefore, since the container 6 is stored in the bag 8 with the developing powder discharge opening 7 facing upward, the container 6
The developer powder remaining inside the housing 1 and the developer powder attached to the container 6 can be removed from the housing 1 without overflowing into the vicinity of the insertion opening 19.
It can be removed from 3.
このように上記構成を採ることにより、現像粉
の補給は容器に付着および残留する現像粉を挿入
口付近に溢すことなく行える。また現像粉は一度
に均一に奥行方向まで補給し得る。つまり補給に
要する時間を大幅に短縮できる。また常に現像粉
を均一に補給することができるために、一定の画
像品位を得ることができる。 By employing the above-mentioned configuration, developer powder can be replenished without the developer powder adhering to and remaining in the container overflowing into the vicinity of the insertion opening. Further, the developer powder can be uniformly replenished to the depth direction at once. In other words, the time required for replenishment can be significantly reduced. Further, since developing powder can be constantly and uniformly replenished, a constant image quality can be obtained.
以上説明したように本考案によれば、現像粉を
挿入口付近に溢すことなく現像粉の補給が行え、
操作性を向上することができる。また現像粉が現
像粉供給の奥行方向に均一に補給され一定の画像
品位を得ることができる。 As explained above, according to the present invention, developer powder can be replenished without overflowing the developer powder near the insertion port.
Operability can be improved. Further, the developer powder is uniformly replenished in the depth direction of the developer powder supply, and a constant image quality can be obtained.
更に、袋８は可撓性材料で構成され、且つカー
トリツジ４と一体に設けられており、袋８がカー
トリツジ４の挿入時に蛇腹状に収縮することがで
きるので、カートリツジ４を現像装置から抜き出
すだけで袋８内に収容することが可能となる。 Further, the bag 8 is made of a flexible material and is provided integrally with the cartridge 4, so that the bag 8 can contract like a bellows when the cartridge 4 is inserted, so that the cartridge 4 can be simply removed from the developing device. It becomes possible to accommodate it in the bag 8.
従つて、操作者は、極めて簡便な操作を行なう
のみで、カートリツジ４を袋８内に回収すること
ができる。更に、袋８を折畳んで収納する作業も
必要としない。 Therefore, the operator can collect the cartridge 4 into the bag 8 by performing an extremely simple operation. Furthermore, there is no need to fold and store the bag 8.
尚、上述の実施例にあつてはカートリツジのシ

てカートリツジの装着作業をさらに簡便にするこ
とができる。 In the above-mentioned embodiment, a type in which the sealing material of the cartridge is peeled off has been described, but the present invention is not limited to this. For example, a type in which the sealing material is slidably incorporated into the cartridge is described. A similar effect can be obtained by using Further, if this sliding type is adopted, the operation of reversing the cartridge becomes unnecessary, and therefore, the work of installing the cartridge can be further simplified.
