PURPOSE:To feed smoothly a magnetic pulverulent body by a suitable quantity each, by forming a variation magnetic field in a feed path on which a lot of communicating partition chambers are formed. CONSTITUTION:A magnetic toner is supplied by an almost fixed quantity each to the bottom part of a partition chamber 4a from a supply port 1b of a hopper by its own weight, and when the end part of a magnet 5a placed so as to freely rotatable in the vicinity of the upper part of its outside approaches a wall 2a, it is attracted upwards and is adsorbed to the inside face of the wall 2a, and as the magnet 5a rotates, said toner passes through the upper communicating port and moves to the upper part of an adjacent partition chamber 4b, its movement is obstracted by a partition wall 3b, and it stays in the vicinity of its root. On the other hand, the magnet rotates continuously as it is, and when the adjacent end part recedes, the adsobed toner drops down to the bottom part of the partition chamber 4b by its empty weight, and when it is accumulated to some extent, it passes through the lower communicating port by its empty weight and moves like tumbling down to the bottom part of an adjacent partition chamber 4c. Thereafter, the same operatin is repeated, the magnetic toner moves to an outlet 2c through partition chambers 4d-4g from the partition chamber 4c, becomes a desired uniform flow and is spplied to a desired place. |
