の現像装置。 a developer tank disposed around the photoconductor; a magnet roller that is internally supported on the photoconductor side of the developer tank and has a plurality of magnetic poles; The developing tank includes an agitation roller rotatably supported via an agitation shaft, and a developer adjustment piece disposed above the magnet roller to regulate the amount of toner scattering onto the photoreceptor. A sink plate is provided above the roller and on the side farther from the photoreceptor than the adjustment piece for returning the developer regulated by the developer adjustment piece to the upper side of the stirring roller. The magnetic pole is arranged so that a line segment connecting it to the roller shaft is located closer to the stirring roller than a line segment connecting one end of the sink plate on the photoreceptor side and the roller shaft of the magnet roller. Copying machine developing device.
