Introduction
Yoshihiro Ogata is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of electrophotographic technology, holding a total of 9 patents. His work focuses on developing devices that enhance the efficiency and quality of image processing in printers and copying machines.
Latest Patents
One of his latest inventions is an image developing device designed for use in electrophotographic copying apparatuses or printers. This device features a developing roller that supplies toner to a latent image formed on a latent image carrier, effectively developing the latent image into a visible toner image. Additionally, it includes a toner supply roller that is independently rotatable and engages with the developing roller to supply toner. The device is designed with electrically conductive components, and an electric potential is applied between the toner supply roller and the developing roller, depending on the charge of the toner.
Another notable invention is a thin film developing device. This device incorporates a developing sleeve that rotates to transport a film of charged developer past a developing station. The film of developer is applied to an electrostatic latent image for development. A sponge roller is also included, which is pressed against the developing sleeve to supply developer and remove any residual developer. The design ensures that a desired voltage difference is maintained between the developing sleeve and the sponge roller, allowing for effective charge discharge.
