Title: Innovator Kazufumi Ishida: Pioneering Image Forming Technologies

Introduction

Kazufumi Ishida, an esteemed inventor based in Sunto Shizuoka, Japan, has made significant contributions to the field of image forming technologies. With a total of 11 patents to his name, Ishida's work has enhanced the efficiency and functionality of imaging devices, impacting various industries.

Latest Patents

Ishida's latest patent focuses on an advanced image forming apparatus. This innovative apparatus comprises an image carrier, exposure device, developing device, primary transfer device, secondary transfer device, and control unit. The exposure device plays a vital role by exposing the image carrier to create an electrostatic latent image. The developing device then transforms this latent image into a toner image using toner. The primary transfer device primarily transfers this toner image to a transfer body, while the secondary transfer device applies a transfer bias to seamlessly transfer the toner image to the recording medium. The inventive control unit enhances overall performance by applying a cleaning bias to the secondary transfer device to eliminate residual toner post-transfer. In cases where the toner image fails to be transferred at a predetermined timing, the control unit initiates a first cleaning process until subsequent operations are ready to commence.
