Abstract
PURPOSE:To carry toner stably at any time, by setting the gap between the tip of a guide member and a nonomagnetic cylinder a little bit greater than that between a doctor member and the nonmagnetic cylinder. CONSTITUTION:Stable toner supply is performed by positioning guide plate 7' nearly in the tangent direction of nonmagnetic sleeve 2. Namely, magnetic toner 5 led out of toner tank 4 by the magnetic suction force of permanent magnetic roll 3 reaches the tip of guide plate 7, but the revolving magnetic field of permanent magnetic roll 3 operates upon guide plate 7' there horizontally and successively. Then, the magnetic toner vibrates horizontally and reciprocally, so that the stable toner supply is possible.
