れる。 For example, a rectangular parallelepiped container with a bottom shaped like the supply port at the top of the hopper and an opening formed in the bottom is filled with developer, and the opening is removably sealed with an airtight seal. Stopped developer cartridges are known. This developer cartridge is placed on top of the hopper with its opening aligned with the supply port of the hopper, and when the seal is peeled off in this state, the developer in the container falls into the hopper and is replenished.

ている。 Furthermore, Japanese Patent Application Laid-open No. 55-21028 discloses that a rectangular parallelepiped container having a substantially trapezoidal cross section has an opening extending in the longitudinal direction at the bottom thereof, and a hermetic seal is removably sealed in the opening. A developer cartridge is shown. This developer cartridge is rotatably mounted on the side surface of the hopper with the opening facing upward, and after peeling off the airtight seal member in this mounted state, the developer cartridge is moved approximately 1/2 inch toward the hopper.
By rotating the container four times, the developer in the container falls and is replenished from the opening into the hopper.

のではない。 Further, one side of the opening of the developer cartridge is engaged with one side of the supply port of the hopper,
It is possible to improve the alignment and sealing between the opening and the replenishment port, but when peeling off the seal between the opening and the replenishment port, it is necessary to press the developer cartridge and improve the seal. It has to be held, and the operability is not as good as being able to operate it with one hand.

できない。 Moreover, in the above-mentioned Japanese Patent Application Publication No. 55-21028,
After peeling off the seal on the opening, the developer cartridge is rotated and the opening is placed over the hopper supply port, which improves workability to some extent, but effectively prevents developer from scattering. I can't.

Further, a longitudinal opening 1e (see FIG. 4) is formed in a part of the lower surface 1c (see FIG. 3) of the cylinder 1,
A hermetic seal 2 is thermally welded to the periphery of the opening 1e. This airtight seal 2 has a seal that is perpendicular to the longitudinal direction of the opening 1e and that is pulled toward the side opposite to the rotational engaging portions 3, 3' (the side facing the other side 5' of the upper surface 1b). A hand portion 21 is extended. This pull portion 21 is connected to the upper surface 1.
It is folded back onto the upper surface 1b along one side 5 of b, and its tip is fixed with an adhesive tape 6.

８周辺に収納される。 Next, when the adhesive tape 6 is peeled off and the pull part 21 of the sealing seal 2 is pulled diagonally upward (in the S direction in FIG. 3), one side 5 of the developer cartridge A will also move upward due to this tensile force. However, since the rotationally engaging parts 3, 3' engage with the rotationally engaging parts 7, 7' of the hopper b and the movement of the developer cartridge A is restricted, the developer cartridge A will not leave Hopper B. Therefore, the tensile force is applied directly to the heat-welded part of the hermetic seal 2, and the heat-welded part of the hermetic seal 2
As shown in the figure, it is peeled off from one end of the folded portion. As a result, the airtight seal 2 of the opening 1e
The developer D gradually falls from the peeled part and is stored around the developer supply roller 8 provided below in the hopper B.

The developer cartridge A has a counterclockwise direction (Fig. 3,
R direction) is applied, but as described above, the flat plate portion 1c' of the lower surface 1b of the developer cartridge A comes into contact with the side surface 9 of the hopper B, and its rotational movement is restricted, and the flat plate portion 1C' is strongly Hopper B side 9
Since the hopper B is pressed against the hopper B, the sealing effect of the hopper B is improved.
ホツパーＢ内の現像剤が不足した場合は、空に
なつた現像剤カートリツジＡをホツパーＢ内から
取り除き、新しい現像剤カートリツジＡを上述の
手順でホツパーＢ内に装着する。 When the developer in the hopper B is insufficient, the empty developer cartridge A is removed from the hopper B, and a new developer cartridge A is installed in the hopper B according to the procedure described above.
