PURPOSE:To prevent an error in the charging order of developer components by making two developer storage parts independent of each other, and providing special sealing mechanism to their opening parts. CONSTITUTION:A storage container 40 is provided with a storage chamber 41 for magnetic particles 20 and a storage chamber 42 for a nonmagnetic developer 24. Openings 46 and 47 corresponding to the storage chambers 41 and 42 are formed in a bottom plate 45, and the openings are normally sealed with sealing members 48 and 49. The sealing members 48 and 49 are tape-like flexible bodies (e.g. synthetic resin sheet) which are wider than the openings 46 and 47, >=2 times as long as the openings, and high in tensile strength. The opening 46 is sealed with the sealing member 48, and the remaining seal member 48a is folded to the front end side. A grip member 50 is fitted fixedly to the end part 48c of the folded sealing member 48a. On the other hand, the end part 49c of the folded member 49a of the sealing member 49 is folded back to the end part 45a of the bottom plate. This end part 45a is engaged with the fitting gap opening part of the grip member 50 fitted to the member 48a. Consequently, the end part 49c of the member is hidden behind the fitting gap opening part of the grip member 50. The grip 50 is drawn out to supply magnetic particles 20 and then the end part 49c is drawn out to supply the nonmagnetic developer 24 to the container 14 individually. |
