Claims

[Claims for Utility Model Registration] 1. A developing device main body is detachably attached to a copying machine main body, and the developing device main body has a developer tank and a supply port for supplying developer to the supply port of the developer tank. A developing device for a copying machine comprising a developer replenishment tank, wherein the replenishment tank has a transport position during transport of the copying machine main body in which its replenishment port is in a position that does not correspond to the supply port;
The replenishment port is movable with respect to the developer tank between a usage position in a position corresponding to the supply port, and a developer sealing device for sealing the replenishment port is provided, and the replenishment tank 1. A developing device for a copying machine, characterized in that a pressing member is provided for pressing a sealing device against a mouth wall of a replenishing port in a transportation posture. 2. A developing device for a copying machine, wherein the supply tank according to claim 1 is rotatably movable relative to the developing tank according to claim 1 between a transportation position and a use position. 3. The sealing device according to claim 1 is provided with a sealing member removably affixed to the mouth wall of the supply port according to claim 1, and a winding shaft for winding up the sealing member, A developing device for a copying machine, characterized in that the supply tank according to claim 1 can be switched from a transportation position to a usage position by rotating a shaft.
