Title: Takashi Kakuhashi: Innovator in Image Formation Technology

Introduction

Takashi Kakuhashi is a notable inventor based in Hitachi, Japan. He has made significant contributions to the field of image formation technology, particularly through his innovative patent that addresses offset prevention in fixing devices.

Latest Patents

Kakuhashi holds a patent for a "Fixing device improved in offset-prevention." This invention involves a fixing device in an image formation apparatus that includes a heating roller and a backup roller. Each roller is coated with single silicone rubber layers around their core bars, which possess a volume resistance value of 10 &OHgr;·cm or more. The heating roller is charged with electricity of the same polarity as the toner particles due to frictional electrification during the feeding of a recording medium. The heating and backup rollers are polarized in a manner that is reverse to the polarity of the recording medium. This design ensures that the quantity of charged electricity on the backup roller is greater than that on the heating roller, effectively preventing offset during the fixing of toner images onto various types of recording media.
