Title: Innovations by Toshiyuki Koshio: Advancements in Toner Technology
Introduction
Toshiyuki Koshio is a notable inventor based in Tokyo, Japan, recognized for his contributions to the field of toner technology. With a total of two registered patents, Koshio has made significant strides in enhancing the composition and functionality of toner used in printers and photocopiers.
Latest Patents
Among Koshio's most recent patents is a method described as a *Process for preparing toner or capsule toner for use in.* This innovative process involves kneading a mixture of a colorant and a binder compound that has an aliphatic hydrocarbon long chain, ensuring that the melt viscosity remains relatively low. The procedure utilizes solid media such as balls or beads to create a uniform mixture where the colorant particles are disintegrated to a size of 5 micrometers or below. From this uniform mixture, solid particles suitable for use as toner can be formed and encapsulated to create capsule toner.
Another significant patent is the development of *Encapsulated electrostatic toner with locally attached non-magnetic particles.* This encapsulated toner is designed for the development of electrical latent images, consisting of a core particle containing both a colorant and a soft solid material. Additionally, inorganic fine particles are attached to the core's surface, while a shell coats both the core particle and the fine particles. These inorganic fine particles serve to reinforce the encapsulated toner through a thin shell and can be attached via dry-mixing. The resulting core particles, enhanced with inorganic particles, may be further coated with a shell resin through phase separation.
