Title: The Innovative Contributions of Koichi Tsunemi
Introduction
Koichi Tsunemi is a notable inventor based in Chofu, Japan, recognized for his significant contributions to the field of image formation technology. With a total of six patents to his name, Tsunemi has made advancements that enhance the efficiency and quality of image processing systems.
Latest Patents
One of Tsunemi's latest patents is an image formation apparatus using a liquid toner. This apparatus comprises a photosensitive body and a transfer medium that receives an image made of a liquid toner formed on the photosensitive body, further transferring the image to an image formation medium. The transfer medium features a structure where a conductive rubber layer and a polymer surface layer made of a silicone resin containing a conductive metal oxide are formed on the surface of a roller main body. This design ensures a surface resistance of 10E10 Ω/□ or less. Another significant patent is for an electrophotographic machine that includes a backup roller disposed within an intermediate transfer medium. This machine is equipped with an image forming device that creates a latent electrostatic image on a latent image carrier, a developing unit that develops a visible image from the latent electrostatic image using a liquid developer, and a pressure roller that applies pressure to the intermediate transfer medium. Notably, the contact pressure between the intermediate transfer medium and the pressure roller is greater than that between the intermediate transfer medium and the latent image carrier.
