Abstract: PURPOSE:To perform conveyance of a magnetic powdery material through simple and small constitution in a state that impurity is removed from granules containing impurity by a method wherein other operation, such as ultrasonic vibration and gravity, than a magnetic force 18 used for a conveyance passage for the powdery material. CONSTITUTION:A magnetic force generating means 2 is disposed above a conveyance pipe 3 and in a position facing to an opening 3' and devices to nip a piezoelectric element between electrodes are mounted on the conveyance pipe 3 as a vibration generating means 1 are arranged at a distance therebetween. By applying a given alternating current by each of high frequency AC sources 6, vibration owing to deformation of the piezoelectric element is generated. When a used magnetic toner 4 recovered from an image forming device is fed to the conveyance pipe 3, the toner 4 is advanced in the direction of an arrow mark as the toner is disentangled through vibration of a pipe.

In this case, since impurity is formed of a non-magnetic material, physical coupling with the toner is weakened by vibration and the impurity is separated under gravity and dropped through the opening 3' and collected in a container 5.
