Title: Noriaki Egawa: Innovator in Electrophotographic Technology

Introduction

Noriaki Egawa is a prominent inventor based in Komae, Japan. He has made significant contributions to the field of electrophotography, holding a total of 14 patents. His work focuses on enhancing the efficiency and quality of electrophotographic members and image forming apparatuses.

Latest Patents

One of Egawa's latest patents is for an electrophotographic member that features a surface with excellent abrasion resistance. This innovation allows toner to have an increased charge amount, resulting in uniform and high transfer efficiency. The electrophotographic member includes a surface layer made from at least one of an acrylic resin and methacrylic resin, along with a positively chargeable charge control agent. Notably, the surface of this layer is designed to be free from any convex portions exceeding 15 μm in height, which could interfere with performance.

Another significant patent involves a transfer belt used in conjunction with a cleaning member and an image carrier. This transfer belt is designed to facilitate the transfer of a developer image from the image carrier. It consists of a surface layer that contacts both the image carrier and the cleaning member, as well as a base layer positioned further away. The surface layer features grooves formed by transferring a predetermined mold shape, extending in a first direction along the moving direction of the transfer belt. The arithmetic average roughness of the surface layer in a specified region is maintained at less than or equal to 0.2 μm.
