摘要： A developing unit includes a developer storage unit, a developer bearing member, an agitation member, a flexible member, and a magnet member. The developer storage unit stores a developer. The developer bearing member develops an electrostatic latent image formed on an image bearing member with the developer. The agitation member agitates the developer in the developer storage unit. The flexible member, disposed in the developer storage unit, is distorted by pressure applied by the agitation member via the developer. The magnet member, disposed on the flexible member, is displaced in response to the flexible member being distorted.
