Title: **The Innovations of Shou Ogawa: A Pioneer in Electrophotographic Technologies**

Introduction

Shou Ogawa, an inventive mind hailing from Okayama, Japan, has made significant contributions to the field of electrophotography. With a total of three patents to his name, his work primarily focuses on advanced materials for carriers used in electrophotographic applications.

Latest Patents

Among his latest innovations, Ogawa has developed notable patents including "Carrier core material and electrophotographic carrier using same" and "Electrophotographic developer." The carrier core material is characterized by a unique composition formula MFeO, which involves the substitution of part of M and/or Fe with Strontium (Sr). This novel material boasts a Sr content ranging from 2500 ppm to 12000 ppm, with an elution rate of less than 50 ppm when tested with pure water at a temperature of 25°C. The development also emphasizes the importance of apparent density, which lies between 1.85 g/cm³ and 2.25 g/cm³, alongside a magnetization threshold when subjected to a magnetic field of 79.58 x 10A/m.

Furthermore, his advancements in the electrophotographic developer emphasize a carrier core material formed with ferrite particles. These particles exhibit a skewness and kurtosis that promotes durability and usability, thus minimizing issues such as cracking or chipping during use. The maximum height of these particles falls between 2.20 µm and 3.50 µm, ensuring effective performance in electrophotographic applications while also reducing the necessity for coating resin.
