Title: Innovator Koushi Suematsu: Pioneering Encapsulated Toner Technology
Introduction: Koushi Suematsu, an accomplished inventor based in Kawasaki, Japan, holds four patents to his name. His contributions to the field of imaging technology, particularly in the development of advanced toners, have paved the way for improvements in printing processes.
Latest Patents: Among his latest innovations is the patent for a pressure-fixable encapsulated toner. This toner consists of capsules where each includes a core with a pressure-fixable component, surrounded by a shell formed by a copolymer containing 95-70% by weight of vinylidene chloride and 5-30% by weight of acrylonitrile. This unique composition enhances the covering property of the shell while ensuring ease of preparation and stable triboelectrical chargeability, developing ability, and pressure fixability to plain paper during repeated service operations.
Another noteworthy invention of Suematsu is a proprietary developer that incorporates a modified silicone oil with an amine on its side chain. The associated development process involves strategically arranging a member that holds an electrostatic image alongside a toner-carrying member. The fixing method in this process involves heating a roller that comes into contact with a toner image comprised of this unique toner blend, with a melt index (MI) ranging from 0.01-10 g/10 min.
Career Highlights: Koushi Suematsu works at Canon Kabushiki Kaisha, a globally recognized leader in imaging and optical products. His work is instrumental in enhancing the quality and efficiency of printing technology through innovative toner solutions.
Collaborations: Throughout his career, Suematsu has collaborated with fellow innovators Tetsuo Hasegawa and Masaki Uchiyama. Their combined expertise contributes significantly to the research and development efforts at Canon, pushing the boundaries of imaging technology.
Conclusion: Koushi Suematsu's inventive spirit and dedication to research make him a pivotal figure in the advancement of toner technology. His latest patents reflect a commitment to innovation, demonstrating the importance of collaboration and creativity in driving progress in the field of imaging.
