6, and a plastic frame member 7 constituting a guide tube fixing means 20, which will be described later, is attached to the lower end of the guide tube 6.

Further, the developer discharge port 4 of the container body 5 is connected to the container body 5.
It is closed by a sealing member 8 that is releasably heat-welded to the lower end surface of the developer 3, which prevents the developer 3 contained therein from spilling and maintains stable developer performance.

The sealing member 8 is folded in half as shown in FIG. 2, and one end 8a of the lower surface thereof is firmly adhered to the frame member 7.

The frame member 7 has a 7 flange portion 1 that protrudes outward and horizontally.
1, and four locking members 1 on the lower surface thereof.
2... and a stopper 13 are integrally protruded,
These constitute the guide tube fixing means 20.

On the other hand, a rectangular replenishment port 9 is provided on the upper surface of the developer container 2.
An elastic member 10 made of foamed polyurethane or the like is attached to surround the elastic member 10, so that the lower surface of the seven flange portions 11 can overlap with the upper surface of the elastic member 110, and the opening of the replenishment port 9 On both side edges, the above-mentioned locking members 12 and
Notch portion 14 for inserting the claw portion 21 of
... is formed.

Further, an elastic member 15 made of polyurethane foam or the like is attached along the inner circumferential edge of the upper end of the guide tube 6 to seal the gap between the container body 5 and the guide tube 6.

Next, the replenishment operation from the developer replenishing container 1 configured as described above will be explained.

First, as shown in FIG.
A lid (not shown) for closing the container is removed in advance, and the developer replenishing container 1 is mounted on top of the lid.
