Title: Kazushige Morita: Innovator in Electrophotographic Technology
Introduction
Kazushige Morita is a prominent inventor based in Ikoma-gun, Japan. He has made significant contributions to the field of electrophotography, holding a total of 13 patents. His work focuses on enhancing the performance and precision of electrophotographic photoreceptors.
Latest Patents
One of Morita's latest patents is for an electrophotographic photoreceptor and method for producing the same. The objective of this invention is to prevent interference fringes in images and allow for precise measurement of the thickness of a layer through optical interferometry. By limiting the surface roughness of a conductive substrate, the invention achieves a maximum peak-to-valley roughness height (Ry) of 0.8 to 1.4 μm, a centerline average roughness (Ra) of 0.10 to 0.15 μm, a ten-point average roughness (Rz) of 0.7 to 1.3 μm, an average peak-to-peak distance (Sm) of 5 to 30 μm, and a peak count (Pc) of 60 to 100. This configuration allows light for exposure to scatter appropriately, preventing interference fringes and enabling high-precision measurement of the photosensitive layer's thickness.
Another notable patent is for a color image forming apparatus. This invention features multiple image forming stations for various development colors, including black. Each station is equipped with a photoreceptor that has a charge transport layer made from a blend of at least two types of resins. The blended ratio of these resins for the black photoreceptor differs from that of the other colors, resulting in greater abrasion resistance for the black photoreceptor. This innovative structure allows for the concurrent use of all photoreceptors for both black and color images.
