Title: Innovations of Yoshihide Shimoda

Introduction

Yoshihide Shimoda is a prominent inventor based in Nara, Japan. He has made significant contributions to the field of electrophotography, holding a total of 12 patents. His work focuses on improving the efficiency and quality of color image forming apparatuses.

Latest Patents

One of his latest patents is for a color image forming apparatus that features multiple image forming stations for various development colors, including black. Each station is equipped with a photoreceptor that contains a charge transport layer made from a blend of at least two types of resins. The unique aspect of this invention is that the blended ratio of the binder resins for the black photoreceptor differs from that of the other colors, resulting in enhanced abrasion resistance for the black photoreceptor. This innovation allows for the concurrent use of all photoreceptors for both black and color images.

Another notable patent is for an electrophotographic photoreceptor and its production method. This invention controls the increase of voltage (VL) to below 15 V by adjusting the content ratio of charge transporting materials within a specific range. The design ensures minimal reduction in image concentration, thereby enhancing the overall quality of the electrophotographic process.
