In a developing device of a copying machine equipped with an agitator for use in a copying machine, a side plate is installed inside the side plate at both ends of the rotating shaft of the agitator, and does not generate a force that moves the developer toward the side plate by rotating together with the shaft. A developing device characterized in that a member for preventing developer from being pressed against the shaft is fixedly provided to the shaft. (2) Registration of a utility model characterized in that the developer pressure prevention member is a spiral blade that moves the developer toward the center when the rotation shaft rotates in the rotation direction of the rotation shaft. A developing device according to claim 1. (3) The above-mentioned developer pressure prevention member is a member obtained by dividing an elliptical plate having the same shape and same inclination as the above-mentioned inclined elliptical plate into two along its short axis and removing the half closer to the side plate. A developing device according to claim 1, characterized in that it is a utility model. (4) The developing device according to claim 1, wherein the developer pressure prevention member is a disc provided perpendicularly to the shaft.
