Title: Hiroaki Takenouchi: Innovator in Electrophotographic Technology
Introduction
Hiroaki Takenouchi is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of electrophotographic technology, particularly in the development of innovative fixing methods for wet process copiers. With a total of 3 patents to his name, Takenouchi continues to push the boundaries of imaging technology.
Latest Patents
One of his latest patents is a fixing method for a wet process copier. This method involves developing an electrostatic latent image using a heat-bridging type toner. The resulting toner image is transferred to a paper sheet and fixed by transporting the sheet through a nipping section defined by a heating roller and a pressing roller. Notably, the side of the paper sheet carrying the toner image directly contacts the heating roller, which is made of either monomeric, additive-free RTV or LTV silicone rubbers. The heating roller features an average surface roughness of less than 3 microns.
Another significant patent is an image fixing unit for use in a wet-type electrophotographic copying machine. This unit is capable of forming a latent electrostatic image on a photoconductor element and developing it into a visible toner image using a developer that comprises a carrier liquid and toner particles. The invention includes a non-thermal carrier liquid content reduction device and a thermal image fixing device, which work together to enhance the efficiency of the copying process.
