Title: The Innovative Mind of Shigenobu Osawa

Introduction

Shigenobu Osawa, an esteemed inventor based in Kawasaki, Japan, has made significant contributions to the field of developing devices, particularly in the context of image forming technology. With a remarkable portfolio of seven patents, he continues to push the boundaries of innovation in this domain.

Latest Patents

Among his latest inventions, Osawa has developed a device that includes a developing roller and a conductive member. This innovative developing device features a rotatable image developing roller that feeds a one-component toner to an image forming drum. The arrangement allows for a voltage to be applied to the developing roller while a second, higher voltage is applied to the conductive member, both having the same polarity. This design aims to effectively control component aggregation on the developing roller, thereby eliminating any image/non-image potential difference on the image carrier.

Another noteworthy patent of his involves a developing device that incorporates first and second toner supply means. In this device, a storage portion is designated for holding toner, and a developing roller is responsible for supplying the toner to an image carrier. A unique aspect of this invention is the rotatable supply roller that transfers toner from the storage to the developing roller, creating a thin layer of toner on the developing roller's surface. By applying different bias potentials to both the supply and developing rollers using distinct power sources, Osawa's invention optimizes the performance of the toner supply mechanism.
