Title: Innovations of Kouji Maekawa in Electrophotography
Introduction
Kouji Maekawa is a notable inventor based in Kyoto, Japan. He has made significant contributions to the field of electrophotography, holding a total of 6 patents. His work focuses on developing processes that enhance the efficiency and effectiveness of imaging technologies.
Latest Patents
One of his latest patents involves a development process in electrophotography utilizing carbon black. This two-component type developer comprises an electroscopic fixable toner containing carbon black as the coloring pigment. The coloring power of the carbon black ranges from 100 to 120, and a magnetic carrier is used for developing electrostatic latent images formed on a photosensitive plate. The process allows for the detection of image density corresponding to an imitation original, enabling the toner concentration in the developer to be controlled based on the detected image density. This innovation ensures that the toner concentration remains within an optimum range, enhancing the quality of the images produced.
Another significant patent by Maekawa outlines a developing process for electrophotography using a two-component developer. This process includes feeding a developer to a non-magnetic sleeve, maintaining the developer on the sleeve, and removing the carrier to leave the non-magnetic toner. The final step involves transferring the non-magnetic toner from the sleeve to an electrostatic latent image on the surface of a photoreceptor. This method improves the overall efficiency of the electrophotographic process.
