Title: Youtarou Kakitani: Innovator in Electrophotographic Technology
Introduction
Youtarou Kakitani is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of electrophotography, particularly through his innovative patent related to auto-bias developing processes.
Latest Patents
Kakitani holds a patent for an "Auto-bias developing process and an electrophotographic copying machine." This invention involves a method for developing an electrostatic latent image formed on a photosensitive member. The process includes storing a detected potential to apply a fixed bias potential to a developing electrode plate. A sensor electrode detects the surface potential of the photosensitive member through a developing solution. This potential is then stored in a memory circuit for conversion to a fixed bias potential, which corresponds to the detected potential and is applied to the developing electrode. Additionally, the process features steps to remove any toner that attaches to the developing electrode plate by applying a reverse bias potential when the developing process is not active. It also includes rendering the developing electrode plate electrically floating to remove toner and prevent its deposition onto the surface of the photosensitive member.
