Commercial Applications: Title: Advanced Toner Technology for High-Quality Printing This technology can be used in commercial printers, photocopiers, and other printing devices to improve print quality and longevity of toner cartridges.

Questions about the technology: 1. How does the specific resistance of the external additive particles impact toner performance? 2. What are the advantages of using antimony tin oxide particles in the coat layer of the external additive?

Original Abstract Submitted

A toner contains toner particles. The toner particles each include a toner mother particle and an external additive attached to the surface of the toner mother particle. The external additive contains specific external additive particles. The specific external additive particles each include an aluminum oxide particle and a coat layer covering the surface of the aluminum oxide particle. The coat layers contain antimony tin oxide particles. The specific external additive particles have a powder specific resistance of no greater than 100 Ω·cm. The specific external additive particles have a volume median diameter of 100 nm to 550 nm. The specific external additive particles have surfaces with an arithmetic mean roughness Ra of 8 nm to 45 nm. The specific external additive particles have a content of 0.3 parts by mass to 4.0 parts by mass relative to 100 parts by mass of the toner mother particles.
