Title: **Nobuyasu Honda: Innovator in Electrophotography Toner Technology**
Introduction
Nobuyasu Honda, an influential inventor from Tenri, Japan, has made significant contributions to the field of electrophotography with a total of 13 patents to his name. His innovative work primarily focuses on toner technology, which plays a critical role in the printing industry.
Latest Patents
Among his latest patents, Nobuyasu has developed a toner for electrophotography and a production method for it. One of the notable inventions is a binder resin as the main component of the toner, which incorporates a low molecular weight polypropylene as a separating agent. By encapsulating this binder, he produces a toner that includes wax with a diameter of 0.3 micrometers or less dispersed within, enhancing its performance. This unique composition effectively prevents the setoff phenomenon during the fixing process while mitigating the filming phenomenon over the photoreceptor, thus achieving improved fixing performance.
Another important patent of his is a toner for electrophotography that features a binder resin as the main ingredient combined with a coloring agent. In this innovation, the binder resin is formulated using low molecular weight polypropylene as a separating agent, with an acid value adjusted to 1.0 mgKOH/g or below. Furthermore, the coloring agent possesses a non-oxidation treated surface and maintains a pH of 7.0 or higher. This specific limitation on the added amount and the diameter of encapsulated polypropylene wax ensures prevention against both the setoff and filming phenomena during printing.
