PURPOSE:To surely and readily carry powder without changing its properties by carrying the powder in the shaft direction of a carrying tube by means of rotating the carrying brush. CONSTITUTION:By giving the powder thrust in the longitudinal direction of the carrying tube accompanying with the rotation of the carrying brush 3, the powder can be carried. Even when excessive powder intervenes between the carrying brush 3 and the inwall of the carrying tube, the carrying brush 3 partially displaces and the powder can be carried in a prescribed direction without pressing together since a core wire 1 and a fiber member 2 which constitute the carrying brush 3 are flexible. Thus, the powder can be surely and readily carried without changing its properties. |
