Abstract

PURPOSE:To improve the collecting property for a developer, by providing a turning means for turning a developing tank in the periphery of a turning center axis until a second developing part is positioned at the lower side of a first developing part by an open attitude of an opening/closing part. CONSTITUTION:The second developing part 14 is provided so as to be freely attachable and detachable to and from the first developing part 13 at a supporting axis 11 side of the first developing part 13, and also, a turning means 15 for turning a developing tank 12 in the periphery of a turning center axis 13A until the second developing part 14 is positioned at the lower side of the first developing part 13 by an open attitude C1 of an opening/closing part 10A is provided. In such a state, in case of dumping and replacing the second developing part 14, the developing tank 12 which is holding a horizontal state is turned in the periphery of the turning center axis 13A by the turning means 15, the second developing part 14 is positioned at the lower side of the first developing part 13, and a developer is dropped down and collected by the second developing part 14. In such a way, in a state that the developer has dropped down already into the second developing part 14, the second developing part 14 is replaced,therefore, it can be prevented that the developer is spilt out to the outside of the developing tank 12. In such a way, the collecting property of the developer is improved.
