In a developing device configured to circulate the developer in the axial direction of the developing sleeve, a cylinder is provided rotatably around an axis parallel to the axis of the developing sleeve, and the developer introduced into one end of the cylinder is circulated through the cylinder. A fin body having a spiral shaft guided out from the other end of the cylinder built into the cylinder and supplying the developer to the developing sleeve while slightly biasing the developer toward one end of the cylinder is attached to the outer peripheral surface of the cylinder. A developing device characterized in that a plurality of developer passage openings are formed by the fins which are radially connected to each other and which are adjacent in the axial direction of the cylinder. (2) The developing device according to claim (1), wherein the developer passage openings are located at different positions in the axial direction of the cylinder. (3) A stirring tool unit is formed by the cylindrical member, the helical shaft, and the fin, and the ends of the fins of adjacent ones of the plurality of stirring tool units are made to have different phases around the axis. A fin body that forms the developer passage opening between the stirring tool units, a cylinder body with a continuous cylinder member, and a spiral shaft with a continuous spiral shaft body are integrated with the rotating shaft of the book. The developing device according to claim (1) of the utility model registration, which constitutes an integrally provided agitation supply device.
