Title: **Innovations by Takafumi Aoyama: A Pioneer in Electrophotographic Technology**
Introduction
Takafumi Aoyama, an innovative inventor based in Kumagaya, Japan, has made significant contributions to the field of electrophotography. With two patents to his name, Aoyama's work focuses on improving magnetic toner compositions and electrostatic developing apparatuses.
Latest Patents
Aoyama's latest inventions include a **Preparation Method of Magnetic Toner**. This method outlines a novel approach to creating single component toner compositions essential for developing electrophotographic images. The process involves mixing a binding component with magnetic particles, pulverizing the mixture, and then incorporating carbon black to enhance the toner. The resultant compositions exhibit a resistivity ranging from 4.3 x 10³ to 4.3 x 10⁶ ohm-cm under a D.C. field of less than 20 volts/cm, making them ideal for practical applications.
Another notable patent is the **Electrostatic Developing Apparatus**. This invention details an electrostatic developing system designed to develop latent images on electrostatic copy paper through a magnetic brush developing process. In this apparatus, a magnetic brush of developer is formed on a non-magnetic cylinder. As the cylinder rotates around a stationary permanent magnet with multiple developing magnetic poles, it effectively rubs against the electrostatic copy paper, creating visible images from the latent ones.
