Abstract
PURPOSE: To make the circumferential part of a picture clear by arranging a removing means of removing a toner in one color sticking to the circumferential part of a developed picture in the other color at the post stage of a final developing device.
CONSTITUTION: Edge picture removing device 26, is equipped with nonmagnetic sleeve 42 having the upper exposed inside of housing 41, arranged clockwise rotatably and magnets 43 and 44 arranged stationarily in this sleeve 42 and in housing 41 magnetic carrier 45 is contained. Sleeve 42 is conductive or insulated and magnetic carrier 45, forming the magnetic brush by being sucked to the surface of rotating sleeve 42 by the magnetic suction force of magnet 43, has the amount of sticking toner restrained by doctor 46 and then upstands like tufts by magnet 44 arraged closely to the surface of photosensitive drum 21 to come into frictional contact with the surface of drum 21, so that only the toner weak in sticking force which corresponds to the edge picture will be scratched off.
