Introduction

Eri Yamanishi is a prominent inventor based in Hakui, Japan. She has made significant contributions to the field of electrophotographic technology, holding a total of 4 patents. Her innovative work focuses on improving the efficiency and effectiveness of liquid toner applications in printing technologies.

Latest Patents

One of her latest patents is a full-color electrophotographic apparatus using liquid toner containing resin. This invention is designed to form a toner image on an intermediate transfer member, which is then heated to a specific temperature to facilitate the transfer of the image to a printing medium. The apparatus includes a carrier-removing roller that utilizes an electric field to remove the carrier while packing softened toner. Additionally, the backup roller assists in transferring the toner image to the printing medium by applying bias and heating the medium beforehand. This innovative approach helps prevent thermal damage to the photoconductor member.

Another notable patent is a method and device for cleaning a liquid development electrophotographic device. This cleaning apparatus effectively removes residual liquid developer from the intermediate transfer member after an image has been transferred to the printing medium. It includes a cleaning-liquid application device, a bias voltage application device, and a collection device to ensure efficient cleaning without transferring an image.
