PROBLEM TO BE SOLVED: To provide the developing device of an image forming device provided with a toner residual amount detector capable of detecting the residual amount of toner with high accuracy. SOLUTION: A rotating member 38 provided on a front side in the rotating direction of a toner stirring member 34, movably fixed to the rotation shaft 33 of the member 34, and rotating by being pressed from back to the member 34, an interference member 41 interfering in rotary motion in the case the member 38 rotates downward, and a magnetic force detecting unit 40 detecting a magnetic body 39 provided on an area where the member 38 rotates downward and provided on the member 38 are constituted, so that the toner residual amount is decided based on the detection result of the unit 40. |
