Latest Patents
One of his latest patents is a toner composition for electrophotography. This invention provides a toner composition primarily comprising a binder resin that contains at least 20% by weight of a urethane-modified polyester resin. The resin is obtained by reacting a polyester resin with an isocyanate compound, resulting in a gel fraction that ranges from 2 to 75% by weight. This toner composition exhibits excellent melting properties suitable for fast reproduction, including a low lower limit of the fixing temperature and a wide range for permitted fixing temperatures. Additionally, it demonstrates remarkable resistance to blocking, carrier contamination, and superior image-forming properties.
Another notable patent is related to an electrophotographic toner and its production process. This invention aims to provide a toner for high-speed copying machines that can fix toner at lower temperatures. The toner comprises a vinyl resin with a wide molecular-weight distribution and a specific glass transition temperature. It also includes a glycidyl compound that enhances the fixing property, offset resistance, and blocking resistance, particularly improving grindability during toner production.
