Latest Patents

Among her latest patents are innovative solutions such as an image-forming method and magnetic toner. The image-forming method she developed ensures stable image density regardless of varying use environments. It effectively prevents image defects like fogging, tailing, or transfer voids, even when applied to a developing sleeve with a reduced diameter. This method involves a latent image bearing member and a toner bearing member that carries a magnetic toner on its surface. An alternating field is applied between these members, allowing for the development of an electrostatic latent image with the magnetic toner. The toner bearing member is designed with a specific diameter, while the magnetic toner possesses particular circularity and compressibility. The total energy of the toner, measured with a powder flowability apparatus, meets specific criteria.

Another notable patent addresses issues of thin image density and sweeping that occur when using a toner carrying member with a small diameter. This image-forming method includes several steps: charging, electrostatic latent image formation, developing, transferring, and fixing. The magnetic toner used in this method has a specific weight average particle diameter and intensity of magnetization in a defined magnetic field. Additionally, the surface free energy of both the magnetic toner and the toner carrying member adheres to specific relationships.
