実用新案登録請求の範囲第１項記載の現像装置。[Claims for Utility Model Registration] (1) A developer chamber provided with a stirring roller to supply developer to the developing roller and to which the developer returns after development, and a developer chamber into which the developer flows from the developer chamber. A developing device having a toner addition chamber into which toner falls from a toner hopper, and a pre-mixing chamber equipped with an agitation roller to agitate the developer flowing from the toner addition chamber and send it to the developer chamber, wherein the developer chamber and A slit is provided in the partition wall between the toner addition chambers, and by keeping the developer level in the developer chamber above the upper edge of the slit, developer is transferred from the developer chamber to the toner addition chamber through the slit. A developing device characterized by a flow-in process. (2) The flow of the developer from the toner addition chamber to the premixing chamber and the feeding of the developer from the premixing chamber to the developer chamber are between the partition wall of the toner addition chamber and the premixing chamber and the outer wall of the developing device, respectively. and the gap between the partition wall of the premixing chamber and the developer chamber, and the outer wall of the developing device, and the toner concentration sensor facing the premixing chamber is provided on the outer wall of the developing device. Developing device according to item 1.
