TONER FOR USE IN IMAGE-FORMING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18544218 titled 'TONER FOR USE IN IMAGE-FORMING
The patent application describes a toner containing a toner particle with a binder resin and an external additive. A peak corresponding to boric acid is detected in ATR-IR analysis of the toner particle using germanium as an ATR crystal in an ATR method. The external additive includes a hydrophobized fine alumina particle produced by surface-treating a fine alumina particle with a hydrophobic treatment agent.
- The toner particle contains a binder resin and an external additive.
- A peak corresponding to boric acid is detected in ATR-IR analysis using germanium as an ATR crystal.
- The external additive includes a hydrophobized fine alumina particle with specific properties.
- The hydrophobized fine alumina particle has a hydrophobicity of 50-90, volume resistivity of 1.0×10^9Ω·cm or less, and a specific rate of atoms originated from the fine base particle.
Potential Applications: - Printing industry for high-quality prints. - Photocopying machines for improved toner performance.
Problems Solved: - Enhanced toner properties for better printing results. - Improved durability and longevity of toner particles.
Benefits: - Higher quality prints with precise toner application. - Increased efficiency in printing processes.
Commercial Applications: - Toner manufacturing companies can utilize this technology to produce advanced toner products for various printing applications.
Questions about the technology: 1. How does the presence of boric acid in the toner particle impact its performance?
Boric acid can act as a cross-linking agent, improving the mechanical properties of the toner.
2. What are the specific benefits of using a hydrophobized fine alumina particle in toner production?
The hydrophobized fine alumina particle can enhance the toner's dispersibility and charge control.
