Abstract
PURPOSE: To enable selection of a charged toner with a one step magnetic roller and to render a device compact, by using a selection plate with an applied voltage of polarity opposite to that of the charged toner.
CONSTITUTION: Toner 1 is attached from hopper 11 to charged plate 6 by the magnetic force of magnetic roller 5, and as roller 5 rotates in direction P, toner 1 on plate 6 moves in direction Q, and during the movement, charged with corotron 12. Then, toner 1 moves forward to selection plate 10, and since the interval between plate 10 and roller 5 is made larger than that between plate 6 and roller 5, uncharged toner 1' drops to toner receiver 13. On the other hand, since opposite polarity voltage is applied to plate 10, toner 1 is attached to plate 10, and moves onto fixed plate 8 of the side of roller 5 at the end of plate 10. Subsequently, toner 1 moves in direction R, while forming magnetic brush 4 on sleeve 8, and develops latent image surface 3' on contacting to latent image forming drum 3.
