PURPOSE:To prevent toner leakage by forming opening parts to be connected to each other on an inner cylinder and an outer cylinder which are engaged with each other so as to be relatively rotated, sealing the opening of the inner cylinder when both opening parts stop at the disconnection position. CONSTITUTION:In the powdery particle case, the inner cylinder 1 consisting of a cylindrical iron can whose both ends are closed is engaged with the outer cylinder 2 consisting of a cylindrical iron can whose one end is opened and an opening part 4 divided into two parts at a cut residual part 3 on the center is formed on the peripheral wall of the inner cylinder 1. On the other hand, an opening part 5 slightly larger than the opening part 4 of the inner cylinder 1 is formed on the peripheral wall of the outer cylinder 2. Both end edges of a flexible seal member 5 are fixed on the outside of the inner cylinder 1 adjacent to the opening 4 and the inside of the outer cylinder 2 adjacent to the opening 5 with double-sided tape or the like respectively. In such constitution, toner leakage is prevented. |
