真装置の磁気ブラシ現像装置。 Inside the rotating roll, several magnets extending in the roll axis direction are fixed to the inner peripheral surface of the roll, and the magnetic developer is transported by a transport roll whose outer periphery is made of non-magnetic material and can rotate. A magnetic brush developing device is configured to transfer the developer conveyed to a developing roll, in which the length of the magnet at the facing portion of the developing roll and the photoreceptor (in the roll axis direction) corresponds to the length of the printing on the photoreceptor. In a magnetic brush developing device for electrophotography, which is determined by the width, at least one of the magnets other than the photoreceptor and the developing roll facing portion is arranged so as to be approximately the same as the spacing between the side plates of the developing device. Magnetic brush developing device for electrophotographic equipment.
