Latest Patents

One of Katoh's latest patents is a developer detection device and printer. This invention features a detection mechanism equipped with a sealing member made of elastic material. This design prevents toner leakage between the pierced wall surface of a toner tank and a second side plate on the rotating shaft. The sealing member's flat splicing surface closely contacts the second side plate, which can be coated with a high lubricant member to minimize frictional forces. When the sealing force is strongly compressed, the sealing member effectively prevents toner from reaching the sliding surface.

Another notable patent is a developing apparatus that includes recessed sections on the developing roller. This apparatus is designed to control the developer on a developer supporter to a prescribed thickness using a one-component developer. The surface of the developer supporter features recessed sections that receive the developer, ensuring that the density of particles entering these sections and the nip width between the developer control member and the developer supporter meet specific relationships for optimal performance.
