Title: Akihiko Ishii: Innovator in Toner Transfer Technology
Introduction
Akihiko Ishii is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the field of imaging technology, particularly in toner transfer devices. With a total of 3 patents to his name, Ishii's work has advanced the efficiency and effectiveness of printing technologies.
Latest Patents
Ishii's latest patents include a conductive roller transfer device designed to improve transfer efficiency. This device features a roller made of a conductive rubber foam material with a resistivity of more than 107 Ω.cm. In the toner image transferring process, a constant current is applied to the roller, allowing for the transfer of a charged toner image to paper at a desired efficiency, regardless of the paper size. To mitigate toner pollution on the roller, a constant voltage with an opposite polarity is applied, ensuring that any residual toner does not stain the paper.
Another significant patent is for a color picture image formation device that develops latent images. This device comprises multiple photosensitive body drums and image formation sections, each equipped with charge units, exposure units, and developing units for various colors. The intermediate transfer body holds the toner powder images and transfers them to recording paper, where they are fixed by a dedicated unit. The design includes a multi-layer structure for the intermediate transfer body, enhancing its functionality.
