補正の性御を実行することを特長とする現像装置[Claims for Utility Model Registration] (1) Toner is transferred by rubbing a magnetic developer consisting of toner and carrier held on the outer periphery of a developing sleeve against an electrostatic latent image on a photoreceptor. In a developing device that performs a developing process, a plurality of magnetic developer position detection sensors are arranged in the longitudinal direction of the developing device and detect the amount and height of the magnetic developer; A developing device comprising: a control means for controlling a stirring member and correcting deviation of the magnetic developer within the developing device. (2) In the developing device according to claim 1, the stirring member includes a paddle and a screw conveying member, and the control means controls rotation of the stirring member to correct deviation of the magnetic developer. A developing device. (3) The developing device according to claim 1, characterized in that the control means executes the control of bias correction of the magnetic developer based on the detection signal of the developer level detection sensor even when the copying process is stopped. developing device
