Abstract

PURPOSE:To exactly collect a developer, by constituting so that the respective different poles are opposed to each other when collecting the developer, and the respective same poles are opposed to each other when cleaning, in a magnet constituted of 2 magnet pieces. CONSTITUTION:When attracting a developer, a cleaning magnet 12 is drawn out by one magnetic pole portion from a case 13, a magnetic pole of a collecting magnet 11 and a magnetic pole of the cleaning magnet 12 stand face to face with each other by placing a partition plate 15 of the case 13 between them, a magnetic field H is generated on the surface of the magnet, and a developer 16 which has dropped from a developing device is adsorbed as indicated with an arrow (e). On the other hand, when cleaning the developer, the cleaning magnet 12 is pushed into the direction as indicated with an arrow (f), and as for the magnetic poles of both the magnets 11, 12, the respective same poles stand face to face with each other by placing the partition plate 15 between them. In this case, the collecting side surface of the collecting magnet 11 is negated by a magnetic field of the cleaning magnet 12, and the magnetic field is scarcely formed, therefore, the collected developer 16 is separated from the collecting magnet 11 as indicated with an arrow (g).
