    • A method for manufacturing a capsule toner having improved preservability with no deterioration in low-temperature fixability is provided. The method for manufacturing a capsule toner includes a mixed fine resin particle adhering step of adhering mixed fine resin particles including crystalline polyester fine resin particles and amorphous fine resin particles to surfaces of toner base particles to form mixed fine resin particle-adhered particles, a spraying step of spraying a mixed solution of a liquid for plasticizing the toner base particles and the mixed fine resin particles and a crystal nucleating agent, while fluidizing the mixed fine resin particle-adhered particles, and a film-forming step of making a film of the mixed fine resin particles by impact force so that the film is a resin coating layer on the surfaces of the toner base particles.
    • 提供了一种制造具有改进的保存性而不降低低温定影性的胶囊调色剂的方法。 胶囊调色剂的制造方法包括将包含结晶性聚酯树脂微粒和无定形细小树脂粒子的混合精细树脂颗粒粘附到调色剂基础颗粒表面以形成混合的细颗粒粘附颗粒的混合细颗粒粘附步骤,喷涂 在将混合的细树脂颗粒附着颗粒流化的同时,喷涂用于塑化调色剂基础颗粒和混合的细颗粒树脂颗粒和晶体成核剂的液体的混合溶液的步骤;以及成膜步骤, 通过冲击力混合精细树脂颗粒,使得膜是调色剂基础颗粒表面上的树脂涂层。
