Title: Kazuhiro Kotaka: Innovator in Image Forming Technology

Introduction

Kazuhiro Kotaka is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of image forming technology, holding a total of 4 patents. His work primarily focuses on developing devices that enhance the efficiency and effectiveness of printing technologies.

Latest Patents

Among his latest patents are innovations such as a grinding roller, a fixing device, and an image forming apparatus. The grinding roller is designed for use in a fixing device that includes a pair of rotary fixing members. These members rotate while being pressed against each other to create an area of contact, where heat and pressure are applied to a recording medium carrying an unfixed toner image. This process effectively fixes the toner image onto the medium. The grinding roller itself is configured to grind the surface of a toner image-side rotary member, ensuring optimal contact with the unfixed toner image. It features an abrasive grain layer with irregularities, including projections formed by aggregates of abrasive grains, which enhance its grinding capabilities.

Another significant patent involves a developing device within an image forming apparatus. This device includes a toner carrier, or developing roller, which consists of a conductive core and an insulating layer. The design incorporates electrode bars and a pair of electrodes made from conductive metal, strategically placed on the outer surface of the insulating layer. This innovative configuration allows for precise control over the development process, improving the overall quality of the printed image.
