Latest Patents

Shiomi's latest patents showcase his expertise in electrophotographic techniques. One of his noteworthy inventions is an **Electrophotographic Method** that utilizes a single-layer organic photosensitive material drum. This drum features a single organic photosensitive layer with a thickness of at least 25 micrometers, formed on an electrically conducting blank tube that has a surface roughness of no more than 0.6 micrometers. His method allows the drum to rotate at a peripheral speed of no less than 400 mm/sec, effectively executing a comprehensive image-forming process that includes electric charging, exposure, developing, transfer, cleaning by a blade, and removal of electric charge. Remarkably, despite the high-speed rotation and significant frictional force on the cleaning blade, the invention minimizes blade damage and ensures stable image formation over extended durations without compromising cleaning effectiveness.

Another notable patent from Shiomi is related to a **Benzidine Derivative and Electrophotosensitive Material Using the Same**.
