Title: Innovations of Shigrki Uesugi
Introduction
Shigrki Uesugi is a notable inventor based in Unoke-machi, Japan. He has made significant contributions to the field of electrophotography, holding a total of 2 patents. His work focuses on enhancing the efficiency and effectiveness of developing solutions in electrophotographic processes.
Latest Patents
Uesugi's latest patents include a wet type electrophotography apparatus designed to evenly apply developing solution on a developing roller. This innovative apparatus utilizes a non-volatile, high-viscosity, high-concentration liquid toner as a developing solution. It features a photoconductive medium where an electrostatic latent image is formed, along with a prewetting device that applies a film of prewetting solution to the medium's surface. The developing device includes a developing roller that feeds the developing solution to the photoconductive medium, allowing toner particles to deposit on an image carrier based on an electrical field. Additionally, the apparatus incorporates a developing solution applying device with multiple rotating rollers that transport and apply the developing solution effectively.
Another of Uesugi's patents involves a wet type electrophotography apparatus that heats toner on an intermediate transfer medium. This apparatus also uses a non-volatile, high-viscosity, high-concentration liquid toner. It includes a photoconductive medium, a prewetting device, and an intermediate transfer medium for transferring toner particles. A pressure roller is used to transfer the printing medium while a heating device locally heats the surface of the intermediate transfer medium just before contact with the pressure roller. This design allows for efficient heating and fusing of the toner without adversely affecting the photoconductive medium.
