（産業上の利用分野）
本発明は複写機やプリンタ等の電子写真方式を採用する
画像形成装置の現像器に現像剤を補給するだめに用いら
れる画像形成装置の現像剤補給容器に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is applied to a developing device of an image forming device, which is used to replenish developer to a developing device of an image forming device adopting an electrophotographic method such as a copying machine or a printer. Relating to a drug supply container.
（従来の技術）
電子写真方式を採用する画像形成装置では一般に現像剤

ある。This supply container is made of synthetic resin, cardboard, etc., and has a cylindrical or rectangular parallelepiped container body that holds toner inside, and a film that is made of synthetic resin, etc. and seals the opening of the container body for toner supply. It is composed of a seal member having a shape. In order to supply the internal toner from this replenishment container to the developing device, it is necessary to position and fix the replenishment container to the developing device and then peel off the sealing member from the container body.
従ってシール部材は容器本体の開口部口りに剥脱容易（

合がある。Therefore, the sealing member is easily peeled off (
Easy Peel). On the other hand, the sealing member also needs to be able to maintain sufficient sealing performance against shocks such as dropping of the supply container during transportation before use and other changes in environmental conditions. In particular, since the replenishment container is generally used indoors, such as in an office, there is an inconvenience that if the toner inside is scattered outside, it will stain peripheral equipment and also stain the hands and clothes of one worker.

あった。(Problem to be Solved by the Invention) However, the seal member generally has a width of 1000 m.
Since the original film is cut to the width of use, the peripheral edge of the sealing member may be scratched during the cutting process. Furthermore, even when the sealing member is heat-sealed to the container body, high temperature and pressure are applied to the sealing member, which may cause damage to the sealing member depending on the surface condition of the sealing jig or the adhesive surface of the container body. For this reason, when the sealing member is removed from the container body, the sealing member may be cut diagonally or torn, and in the worst case, the sealing member may be cut in the middle and the supply container may not be fully opened, causing the inside of the container to be damaged. There was a problem that a sufficient amount of toner could not be supplied to the developing device.

A developing device 3, a transfer charger 4, etc. are provided, and image light based on the original image is exposed to a photosensitive tram l uniformly charged by the primary charger 2, and the image light is deposited on the photosensitive tram l. A corresponding electrostatic latent image is formed. The electrostatic latent image is visualized and developed by the developer (toner) in the developing device 3, and converted into a toner image. Then, this toner image on the photosensitive drum L is transferred via a transfer charger 4 onto a transfer paper P that has been conveyed through a paper feeding system (not shown). After that, this transfer paper P is sent to a fixing device (not shown),
After the toner image is fixed as a permanent image on the transfer paper P, it is carried out of the machine.

他端部側から外方に突出して引張部３１となっている。FIG. 1 shows an example of this replenishment container 1O. The replenishment container 1O is formed into a box shape from synthetic resin, cardboard, etc., and includes a container body 20 containing toner inside, and a toner supply to the container body 20. A sealing member 30 on a film is attached around a rib 22 provided around an opening 21 for sealing the container body 20. As shown in the figure, the sealing member 30 is bent 180 degrees in the opposite direction at one end of the container body 20, and the bent end protrudes outward from the other end of the container body 20 to form a tension portion 31.

分にできないといったトラブルは生じない。Since the sealing member 30 and the container body 20 are attached to each other through an easy-to-use sealant layer, the sealing member 30 is pulled in the peeling direction A shown by the arrow in FIG. Once removed, the seal member 30 can be peeled off from the container body 20 relatively easily. Here, if there is a scratch on the peripheral edge of the seal member 30 during cutting or a scratch on the seal member 30 during sealing, if it is a normal seal member 30, it will be diagonally shaped as shown in FIG. Although there are cases where the seal member 30 according to the present invention is torn and cannot be opened completely, since the seal member 30 according to the present invention has tear directionality in the pulling direction, a situation where the seal member 30 is torn diagonally does not occur. The sealing member 30 is always peeled off from the container body 20 in the pulling direction. However, the seal member 30
If the intensity of is relatively small, as shown in Figure 2,
There is a possibility that the sealing member 30 is torn off at the adhesive part 11 of the container body 20, but even in such a case, the supply container 10 will be completely opened, and problems such as not being able to replenish the toner from the supply container 10 will occur. do not have.
