摘要： PROBLEM TO BE SOLVED: To reduce toner aggregation in developer.SOLUTION: When a front face 214 of a first bag body 210 and a front face 224 of a second bag body 220 are brought close to each other, toner aggregation is sandwiched between the front faces 214 and 224 to be crushed and collapsed. At the time of returning to a conveyance state, that is, when the front face 214 of the first bag body 210 and the front face 224 of the second bag body 220 are separated from each other, the toner aggregation falls down. Accordingly, the toner aggregation in a developer G is reduced.
摘要翻译：要解决的问题：减少显影剂中的调色剂聚集。解决方案：当第一袋体210的前表面214和第二袋体220的前表面224彼此靠近时，调色剂聚集被夹在前面面214和224被压碎和折叠。在返回到输送状态时，即当第一袋体210的前表面214和第二袋体220的前表面224彼此分离时，调色剂聚集下降。因此，显影剂G中的调色剂聚集减少。
