Latest Patents

Ota’s most recent patents focus on two crucial aspects of toner technology. The first patent, titled "A toner for developing statically charged images," discloses a toner composition that includes a binder resin, a colorant, and a charge-controlling dye. This innovative toner features particles with a circularity ranging from 0.95 to 1.0 and a concentration of dye on the surfaces of the toner particles between 1.0 x 10^-3 to 4 x 10^-3 g/g. These characteristics significantly improve the stability of the toner’s frictional chargeability and reduce contamination of the developing devices.

The second patent outlines a process for the preparation of polymer particles which aids in producing toners with excellent flowability and fixing properties. This process involves using a hardly soluble inorganic dispersant that precipitates at a specific pH, allowing for effective polymerization. By simultaneously employing a colorant with the polymerizable monomer, Ota successfully creates a toner that meets high-quality standards for usage in various printing applications.
