Title: **Keiko Shiraishi: Innovator in Image Processing Technologies**
Introduction
Keiko Shiraishi, based in Susono, Japan, is a prominent inventor known for his contributions to image processing technologies. With a total of 25 patents to his name, he has significantly advanced methods in image removal and forming, demonstrating his commitment to innovation in this field.
Latest Patents
Among his latest patents, Shiraishi has developed an "Image Removing Method," an "Image Removing Device," and an "Image Forming Apparatus." The image removing method involves bringing an outermost layer of a removing member into contact with an image fixed on an image support without using liquid, while heating the image and the outermost layer. This innovative approach allows for the separation of the removing member from the image support, facilitating the removal of the image. The removing member is constructed from a substrate and an outermost layer made of thermoplastic resin, with the image containing a removing agent that decreases the adhesion force when heated.
In addition, his work on a toner and image forming method has transformed the industry. This toner is prepared by dissolving or dispersing constituents that include a modified resin capable of reacting with active hydrogen and a black metallic colorant. Through a reaction with crosslinking or elongation agents in an aqueous medium featuring a resin particulate material, Shiraishi has refined the image forming process for enhanced performance.
