METHOD FOR MANUFACTURING TONER, TONER, DEVELOPER, DEVELOPING APPARATUS, AND IMAGE FORMING APPARATUS

摘要

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.
