ABSTRACT:
A developer container having an opening for discharging a developer contained therein and a sealing surface portion surrounding the opening, is sealed with a sealing member having a sealant layer and applied onto the sealing surface portion of the developer container with the sealant layer. The sealant layer contains a dispersed material therein and the sealing surface portion of the developer container contains a dispersed material, which is mutually soluble with the dispersed material in the sealant layer. The dispersed material in the sealant layer preferably includes a thermoplastic elastomer. The resultant sealed developer container may be provided with a sound seal structure even at a relatively low sealing pressure causing a smaller sealing surface depression of the developer container, which allows re-sealing of the container.
