する現像装置。 A developing container having an opening in a portion facing the photoreceptor, and a rotatable developing sleeve containing a magnet inside the developing container through the opening and with a gap between the upper and lower edges of the opening. The two-component developer stored in the developer container is attracted to the circumferential surface of the rotating developing sleeve by the magnetic force of the magnet, and is conveyed through the upper gap to the developing area facing the photoreceptor, and The toner in the developer is attached to the latent image on the photoreceptor by a main developing pole located opposite the photoreceptor through the developing sleeve to perform development, and the developed developer is applied to the circumferential surface of the developing sleeve. In a developing device that attracts the developer and returns it into the developer container through the lower gap, a magnetic field is formed at the edge of the opening of the developer container and the main developer pole over the entire width of the opening. A developing device characterized in that magnetic members are arranged as shown in FIG.
