TONER FOR USE IN IMAGE-FORMING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240231250 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 hydrophobized fine alumina particle has specific properties such as hydrophobicity, volume resistivity, and atomic composition.
- The toner contains 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.
- The external additive includes a hydrophobized fine alumina particle produced by surface-treating a fine alumina particle.
- The hydrophobized fine alumina particle has specific properties such as hydrophobicity, volume resistivity, and atomic composition.
- The rate of atoms originated from the fine base particle in the hydrophobized fine alumina particle is between 30 atomic % and 70 atomic %.
Potential Applications: - Printing industry for high-quality toner production - Electronics industry for toner used in photocopiers and printers - Chemical industry for developing specialized toner formulations
Problems Solved: - Enhancing the performance and quality of toner particles - Improving the compatibility of toner with printing equipment - Increasing the durability and longevity of printed materials
