2. Description of the Related Art Conventionally, a developer replenishing container has a container main body having a developer replenishing opening mainly made of synthetic resin, paper or the like, and a [polyethylene terephthalate (PET) layer / nylon layer] or [biaxial]. [Stretched polypropylene (OPP) layer / nylon layer] as a base material, which is mainly composed of an ethylene vinyl acetate copolymer (EVA) or the like, which melts by heating to develop a welding force. A heat-sealing film as shown in FIG. 5 in which a welding layer is laminated via a PE layer serving as a cushion material, and this heat-sealing film is heat-welded to a flange portion around the developer supply opening and the like. It is common to seal the storage.

As shown in FIG. 4, the developer is supplied by fitting the developer supply opening of the developer supply container downward into the developer supply section of the main body of a copying machine or the like, and pulling the film by hand or the like. The developer was replenished by opening the developer replenishing opening while peeling off the welded portion between the developer and the container.

However, in the conventional developer supply container, when peeling off the heat-sealed film at the time of replenishment of the developer, the welding strength between [film-container], that is, [weld layer-container adhesion] If the interfacial peel strength of the [surface] is too large, the interlayer strength of the [nylon layer-PE layer] is relatively weak, so that delamination occurs between the [nylon layer-PE layer], which may cause the film to break. was there. Further, in a developer supply container having a developer-integrated cartridge and a shutter member for opening and closing the developer supply opening, the structure is such that the heat-sealing film is in contact with maltprene, a shutter, and the like. Due to the blocking phenomenon of the welded layer, pseudo-adhesion easily occurred between [welded layer-maltoprene, shutter, etc.], and a very large force was sometimes required when the film was peeled off.

[0005] Further, since the surface of the welding layer is rougher than that of PET, OPP or nylon which is a film base, a large amount of the developer easily adheres to the film. Hard to wipe off.
Therefore, if the film is peeled off when the developer is supplied, the surroundings may be stained by the developer attached to the film.

By using the two-layer film 04, the welding layer and the PE layer serving as the cushioning material are removed from the film. Film breakage due to delamination between [nylon layer and PE layer], which occurs when the strength is very high, can be prevented. The surface is rough,
As a result, instead of a welded layer that easily adheres a large amount of developer, the structure is such that the developer is sealed with a nylon layer with a good surface smoothness. It is possible to wipe off
When the film is peeled off at the time of replenishing the developer, the surroundings can be prevented from being stained by the developer attached to the film.

That is, the present invention provides a heat-sealing film by incorporating a welding agent mainly composed of EVA or the like, which melts by heat to develop a welding force, on a surface to be welded around a developer supply opening by coating. This eliminates the need for a welding layer and a PE layer, and allows for heat welding to a container with a configuration consisting only of a base portion. Therefore, the film can be not only a laminated film such as [PET layer / nylon layer] or [OPP layer / nylon layer], but also a single layer film. Films such as aluminum can also be used, greatly increasing the degree of freedom. By using a film having such a configuration, it is possible to completely prevent film breakage due to delamination of the [nylon layer-PE layer], which has conventionally occurred.

Further, the surface of the film is smoother than the conventional welding layer, and the developer is less likely to adhere thereto. Even if the developer adheres, the film can be easily wiped off with a wiping member.
