调色剂及其制造方法、显影剂、显影装置和图像形成装置
摘要：
本发明提供调色剂及其制造方法、显影剂、显影装置和图像形成装置。在树脂微粒附着工序(S3b)中，在粉体流路内使树脂微粒附着于调色剂母粒表面。在喷雾工序(S3c)中，将使调色剂母粒和树脂微粒增塑的液状物质向处于流动状态的调色剂母粒和树脂微粒进行喷雾，然后，在成膜工序(S3d)中，使调色剂母粒和树脂微粒在粉体流路内循环，直到在调色剂母粒上附着的树脂微粒成膜为止，此时，在喷雾工序(S3c)中，喷雾液状物质，以使粉体流路内的LEL浓度系数为0.07～8.12。
摘要（英）：

A method for manufacturing a toner is provided. In a fine resin particle adhering step S1b, fine resin particles adhere to toner base particle surfaces in a powder passage. In a spraying step S3c, flowing toner base particles and fine resin particles are sprayed with a substance in liquid form for plasticizing those particles. In a film-forming step S3d, toner base particles and fine resin particles are circulated repeatedly in the powder passage until fine resin particles adherent to toner base particles are shaped into a film. In the spraying step S3c, the substance in liquid form is sprayed in such a manner that the LEL concentration coefficient within the powder passage falls in a range of from 0.07 to 8.12.
