Title: Kenji Tsujita: Innovator in Electrostatic Image Development

Introduction

Kenji Tsujita is a prominent inventor based in Fujino, Japan. He has made significant contributions to the field of electrostatic image development, holding a total of 7 patents. His work focuses on enhancing the mechanical strength and efficiency of image-developing carriers.

Latest Patents

Tsujita's latest patents include innovative technologies for developing electrostatic images. One notable patent describes an electrostatic image-developing carrier that features a resin coat layer with excellent mechanical strength. This carrier is prepared by applying a mechanical impact force to a mixture of core particles and coating resin particles in a dry condition. The resulting molecular weight distribution chromatogram of the resin coat layer reveals at least one peak or shoulder in a molecular weight range of 1,000 to 20,000. Another patent presents a resin-coated carrier that comprises a silicone resin and a carbon fluoride, which has a BET specific surface area of not more than 100 m²/g. This carrier is designed to impart a proper positive polarity triboelectric charge without the need for a charge control agent.
