Title: The Innovations of Harunobu Tsuiki: A Pioneer in Pressure Sensitive Adhesive Toner

Introduction

Harunobu Tsuiki was a prominent inventor based in Tokyo, Japan, known for his contributions to the field of electrostatic photography. With a unique patent under his name, Tsuiki has made lasting impacts through his innovative ideas and collaborative work in technology.

Latest Patents

Tsuiki holds a significant patent for a "Pressure Sensitive Adhesive Toner of Clustered Encapsulated Porous." This invention is designed for use in electrostatic photography and consists of porous aggregates, where each aggregate includes a cluster of multiple granules of pressure-sensitive adhesive substance. Each granule is encapsulated by a coating film made of a film-forming material. The involvement of inorganic or organic pigments and/or a magnetic substance is essential as they occupy the interstices between the granules and settle on the surfaces of the encapsulated granules. Notably, this toner exhibits no tendency to cohere, cake, or agglomerate, allowing it to be pressure-fixed onto a surface with minimal impression pressure while maintaining the integrity of the electrostatic latent image and forming a clear visible image.
