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.
