装置。 A developing sleeve as a developing member which faces the latent image bearing member on which the electrostatic latent image is formed and is rotationally driven; and a developing sleeve rotatably disposed within the developing sleeve with a gap from the inner circumferential surface of the developing sleeve. magnet and
The developing sleeve is housed with a portion of the developing sleeve facing the latent image carrier exposed, and the developing sleeve is held on the developing sleeve by the magnetic force of the magnet and transported by rotation of the developing sleeve. In a developing device having a casing in which a developer is stored, when the developing device is started, the magnet is rotated after the developing sleeve is rotated, and when the developing device is stopped, the developing sleeve is stopped after the magnet is stopped. A developing device comprising rotation control means.
