PURPOSE:To eliminate the difference in density of a copied image over the overall width of paper by providing two slanting passages where toner falls and providing those passages with opening in prescribed directions, and thus distributing a developer to the axial-line direction of a magnetic roll. CONSTITUTION:Plural partitioning plates 18 for forming the 1st passage 22 which slants downwardly in one direction of the axial line of a magnet roll 12 and plural partitioning plates 20 for forming the 2nd passage 23 which slants downward in the other direction of the axial line of the magnet roll are installed where toner and carriers fall. The exit of the 1st passage 22 is opened under the entrance of the 1st passage 22 adjoining in its slanting direction and the final slanting-directional exit of the 1st passage 22 is opened under the 1st entrance of the 2nd passage 23 adjoining in its slanting direction. Then, the exit of the 2nd passage 23 is opened under the entrance of the 2nd passage 23 adjoining in its slanting direction, and the final slanting-directional exit of the 2nd passage 23 is opened under the 1st entrance of the 1st passage 22. |
