Title: Kohji Ichimura: Innovator in Electrostatic Information Recording
Introduction
Kohji Ichimura is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of electrostatic information recording, holding a total of 5 patents. His innovative work has advanced the technology used in photosensitive members and image recording methods.
Latest Patents
Ichimura's latest patents include a photosensitive member and an electrostatic information recording method. The photosensitive member features an electrode on the front side and a photoconductive layer stacked on it. This design allows for exposure to an electrostatic information recording medium, enabling the formation of an electrostatic charge pattern based on an exposure light pattern. The improvements in layer arrangements and the method of forming the photoconductive layer enhance the sensitivity and contrast ratio of the recorded information.
Another notable patent is his image recording method, which involves controlling electric discharge between a photosensitive member and a charge retaining medium by adjusting the gas pressure. This method allows for image recording while a DC voltage is applied. By preforming an electric charge opposite in polarity to the image forming charge, Ichimura's technique reduces background potential and increases the contrast potential of the electrostatic latent image.
