＆ｔＬをポルトＣで底ｓｈに固着し、底板ｄををり外し
て現像剤を排出口Ｃより排出するようにしている。Therefore, conventionally, as shown in Fig. 1, a discharge port C is formed at the bottom of the developing housing a, the bottom &tL that closes the discharge port C is fixed to the bottom sh with a port C, and the bottom plate d is removed. The developer is discharged from the discharge port C.

ねばならず面倒である。However, with this structure, the bottom &dt-
After removing it, you have to re-tighten the Bordeaux and attach the bottom part d, which is a troublesome work, and since the discharge port C is long, a cloud of developer is likely to form, contaminating the surrounding area1.Furthermore, the inside of the container Since the developer cannot be directly discharged, the developer must be discharged onto paper or the like and then stored in a container, which is cumbersome.

すようにしたもの。OBJECTS OF THE INVENTION To easily drain the developer from inside the developer housing and to contaminate the surrounding area with a developer cloud.Constitution of the Invention Formed at the bottom of the developer housing1. The cylindrical bottom plate has a gold film that can be folded freely over the discharge port, and the bottom plate is folded and connected to the bottom during normal development operation, and the bottom plate is stretched out when the developer is discharged.

形成【である。FIG. 2 on the Fuyu side is a cross-sectional view of the developing device, in which a developing roll 2, a paddle 3, an agitator 4, etc. are provided in the developing housing i.
The developing roll 2 projects outward from the opening 1a of the developing housing 1, a toner box 5 is provided in the upper part 1b of the developing housing I, and a discharge port 6 is formed in the lower ICE.
前記排出口６０周縁には係止溝７が形成しであると共に
、この係止＃７に筒状の底板８が係止する。A locking groove 7 is formed on the periphery of the discharge port 60, and a cylindrical bottom plate 8 is locked in this lock #7.

７に係止しである。The bottom &8 is made of a flexible material such as rubber and has a cylindrical shape that can be folded freely, and the side opening 9 has a large diameter with approximately the same shape as the discharge port 6, and the other side opening 10 is an inlet of the container 11. 12
The periphery 9a of the large-diameter opening 9 is engaged with a latching groove 7 formed on the periphery of the discharge port 6.

- By stretching and connecting the small diameter opening 10 to the inlet 12 of the container 11, the developer is discharged and stored in the container 11 through the discharge port 6 using the cylindrical bottom plate 8 as a guide.
この様であるから、底板８を折シ畳んだり、引き延ばし

に、現像剤クラウドで周囲を汚すことが防止される。Because of this, by folding or stretching the bottom plate 8, the developer in the developer housing 1 can be transferred to the container 11.
The developer can be discharged and stored inside, which simplifies the developer discharge operation and prevents the developer cloud from contaminating the surrounding area.
なお、底板８は蛇腹状の筒体としても良い。Note that the bottom plate 8 may be a bellows-shaped cylinder.
