Zusammenfassung:PROBLEM TO BE SOLVED: To provide an image formation device which can make different types of toner hard to mix in a development device.SOLUTION: An image formation device 10 comprises: an attachment unit 500 to which one storage container 600, in which one type of toner selected from among a plurality of types of toner is stored, is attached; a development device 200; a conveyance device 550 for conveying the toner to the development device 200 from the storage container 600 attached to the attachment unit 500; and a control unit 700. If a storage container 600, in which a different type of toner from the toner stored in a storage container 600 detached from the attachment unit 500, is attached, the control unit 700 stops conveyance of toner by the conveyance device 550 to the development device 200 until concentration of the toner in the development device 200 lowers to be predetermined concentration or less.SELECTED DRAWING: Figure 5 【課題】現像装置内で異なる種類のトナーが混じりにくくすることができる画像形成装置を提供する。【解決手段】画像形成装置10は、複数種類のトナーから選択されたいずれか一種類のトナーが収納された収納容器600の一つが装着される装着部500と、現像装置200と、装着部500に装着されている収納容器600から現像装置200へトナーを搬送する搬送装置550と、制御部700とを有し、制御部700は、装着部500から取り外された収納容器600に収納されていたトナーと異なる種類のトナーが収納された収納容器600が装着された場合は、現像装置200内のトナーの濃度が予め定められた所定の濃度以下となるまでは、搬送装置550による現像装置200へのトナーの搬送を停止させる。【選択図】図5
