像装置。 Inside the housing 2, a sleeve 1 is placed around the magnet 9.
A developing roll 3 of a sleeve rotating type that rotates the photosensitive drum 1 is disposed, and spikes of a two-component developer consisting of toner and carrier are formed on the sleeve 11 to develop the latent image on the photoreceptor drum 1. In the magnetic brush developing device, a magnetic plate 1 is provided at an arbitrary position between the bottom plate 2a of the housing 2 and the developing roll 3.
2 is disposed facing the photoreceptor drum 1, and a magnetic pole side of a permanent magnet 13 different from the developing magnetic pole is attached to the magnetic plate 12.
