PURPOSE:To homogenize and stabilize the thickness of a toner layer and an electrified charge of toner for a long period, by holding the toner by a toner holding member, allowing it pass through an intense magnetic field, while it is carried to a control member of thickness of the toner layer, stirring it and also, correcting the carrying quantity to the control member. CONSTITUTION:A magnetic toner which is held by a toner holding member 27 and reaches a control member 19 is stirred by allowing it to pass through the inside of a magnetic field in its upstream side, and prevented from being pelletized and converted to block. Subsequently, only the stirred toner is further stirred and converted to a thin layer by the control member 19, therefore, it prevents the block-shaped toner from being clogged in a control gap of the control member 19 and the toner holding member 27. Accordingly, a homogeneous toner thin layer 26 is obtained for a long period, and by this homogeneous magnetic toner thin layer, the surface of an image carrying 1 is rubbed. In such a way, an image high in quality uniform in density and less in ground fogging can be obtained. |
