Title: The Innovative Contributions of Takeshi Sumikawa
Introduction
Takeshi Sumikawa is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of image recording technology, holding a total of 14 patents. His work has greatly influenced the development of advanced imaging systems.
Latest Patents
Among his latest patents is an innovative image recording apparatus and method that boasts improved image transfer characteristics. This apparatus includes an image carrying part, a developing part, and an image transferring part. The image carrying part features a surface where an electrostatic latent image is formed. The developing part is responsible for developing this electrostatic image into a toner image by selectively applying toner to the surface of the image carrying part. The image transferring part then transfers the toner image onto a recording sheet or an intermediate image transferring part. Notably, fine particles are uniformly formed on the surface of the image carrying part, with a portion of these fine particles being transferred along with the toner image. These fine particles are smaller in diameter than the toner particles.
Another significant patent involves a developing apparatus that comprises excessive toner separation means. This apparatus utilizes a dual-component developer that contains a magnetic carrier and toner, which is electrically attracted to the magnetic carrier. It selectively transfers the toner to an electrostatic latent image formed on an image support, visualizing the latent image. The developing apparatus features a developer transport member that faces the image support and has a peripheral surface for supporting and transporting the developer. Additionally, a toner excess supplying member is included to supply excess toner to the developer supported on the transport member. An excess toner separator is also part of the design, which separates toner with a small adhesion force to the carrier from the developer to which excessive toner is applied.
