Title: Satoru Hirosaki: Innovator in Developing Technology
Introduction
Satoru Hirosaki is a notable inventor based in Iwatsuki, Japan. He has made significant contributions to the field of developing technology, holding a total of 4 patents. His work primarily focuses on enhancing the efficiency and effectiveness of developing devices.
Latest Patents
Among his latest patents is a charger and an image formation apparatus that utilizes this charger. Additionally, he has developed a device that employs a two-component developer. This innovative developing device is designed to visualize an electrostatic latent image using a two-component developer that includes toner and a magnetic carrier. The technology ensures excellent development while preventing the deterioration of the developer. A key feature of this invention is the preparation of a developer carrier, which involves forming a thin layer of aluminum with a thickness of 3 µm or less on the peripheral surface of a roll-shaped member made of ferrite. The surface roughness Rz of this ferrite roll is maintained at 50 µm or less. Furthermore, N-poles and S-poles are alternately magnetized at a pitch of 50 to 250 µm along the peripheral surface of the ferrite roll. This design allows for uniform intensity in the magnetic poles due to the smooth finishing of the roll's peripheral surface, resulting in a developer layer that is uniformly attracted.
