Title: Masao Fukushima: Innovator in Electrophotographic Technology
Introduction
Masao Fukushima is a notable inventor based in Shiga, Japan. He has made significant contributions to the field of electrophotographic technology, holding a total of 5 patents. His work focuses on improving the efficiency and quality of toner development devices used in copying machines.
Latest Patents
Fukushima's latest patents include a toner development device with an improved scraper. This invention aims to achieve a reproduced image without uneven thickness by stirring developers composed of toner and carrier. The device feeds the developers mixed uniformly in the longitudinal direction along a photosensitive drum. An electrostatic latent image produced on the photosensitive drum becomes visible when it contacts the developers retained in a brushlike state by the magnetic force of a magnet roller. The primary scraper of the scraping means contacts the magnet roller to scrape off the developers, which can then be returned to insufficient portions in a stirring means composed of multiple screw rollers. Another notable patent is a photographic fixing apparatus that feeds photosensitive material between upper and lower inclined guide plates. This apparatus includes a halogen fixing heater and a blower to maintain the photosensitive material out of contact with the lower guide plate.
