摘要：
PROBLEM TO BE SOLVED: To provide a toner that can maintain sufficient transferability and cleaning ability for prolonged periods, prevent filming without causing variation in image nonuniformity or external additive immersion, and excels in stability so that flowability and charge stability are not changed over prolonged periods; and also to provide a developer, a toner container, a process cartridge, an image forming apparatus, and an image forming method. SOLUTION: The toner comprises at least external additives, in which the external additives consist of large-diameter particles and small-diameter particles of the volume average grain size smaller than that of the large-diameter particles. The number of pieces of the aggregates of the external additives left on the sieve of 635-mesh and 452 cm 2 of mesh area, after 0.2 g of the toner on the sieve is blasted with air at a blow pressure of 0.2 MPa from 160 mm above the sieve while being air-suctioned at a suction force of 5 mmHg, and then air-suctioned at a suction force of 20 mmHg, is 5 to 4,500.

摘要（中）：
要解决的问题：为了提供能够长时间保持足够的转移性和清洁能力的调色剂，防止成膜不会引起图像不均匀性或外部添加剂浸渍的变化，并且稳定性优异，使得流动性和电荷稳定性不变化 长时间 并且还提供显影剂，调色剂容器，处理盒，图像形成装置和图像形成方法。 解决方案：调色剂至少包含外部添加剂，外部添加剂由大直径颗粒和体积平均粒径小于大直径颗粒的小直径颗粒组成。 在筛上0.2g调色剂之后，留下635目筛网和452cm SP 2网孔面积的外部添加剂聚集体的数量在吹入时用空气喷吹 在吸力为5mmHg的空气抽吸的同时，筛上160mm的压力为0.2MPa，然后以20mmHg的抽吸力空气抽吸为5〜4,500。 版权所有（C）2007，JPO＆INPIT
