Title: Innovations by Yu Harashima

Introduction

Yu Harashima is a notable inventor based in Hino, Japan. He has made significant contributions to the field of image forming technology, holding two patents that showcase his innovative approach. His work primarily focuses on enhancing the efficiency and effectiveness of image forming apparatuses.

Latest Patents

One of Yu Harashima's latest patents is an image forming apparatus that includes an image former designed to create images on a recording material. This apparatus features a fixer with a first fixing member that has an elastic layer, a second fixing member that forms a fixing nip with the first, and an external heater that heats the first fixing member from outside. This design allows for the image to be fixed on the recording material through heating and pressing at the fixing nip. Additionally, the hardware processor in this apparatus executes a thermal expansion mode, which heats the first fixing member to a higher temperature than during normal printing.

Another significant patent by Harashima is an image forming apparatus and recording medium that includes a transfer mechanism. This mechanism transfers a toner image from a photosensitive member onto a transfer receiving member. It incorporates a conductive member with a resistance that changes its current-voltage characteristic upon energization. The apparatus also features a detector that measures the resistance value when different currents or voltages are applied, allowing the hardware processor to compute the slope of the current-voltage characteristic and determine the deterioration state of the conductive member.
