TONER - A simplified explanation of the abstract

This abstract first appeared for US patent application 18354735 titled 'TONER

Simplified Explanation

The abstract of the patent application describes a toner composition that includes toner particles made up of a binder resin and boric acid. When the toner particles are analyzed using ATR-IR analysis with germanium as the ATR crystal, a peak corresponding to the boric acid is detected. The toner also contains a fatty acid metal salt on the surface of the toner particles, and the presence of boron on the surface is measured to be 0.01 atomic % or less using X-ray photoelectron spectroscopy.

  • The toner composition includes toner particles with a binder resin and boric acid.
  • ATR-IR analysis with germanium as the ATR crystal can detect the presence of boric acid in the toner particles.
  • The toner particles have a fatty acid metal salt on their surface.
  • The amount of boron on the surface of the toner particles is measured to be 0.01 atomic % or less using X-ray photoelectron spectroscopy.

Potential Applications:

  • Toner compositions for use in printing and copying machines.
  • Toner particles with improved properties for better image quality and durability.

Problems Solved:

  • Detection of boric acid in toner particles using ATR-IR analysis.
  • Improved surface properties of toner particles through the presence of a fatty acid metal salt.
  • Accurate measurement of boron content on the surface of toner particles using X-ray photoelectron spectroscopy.

Benefits:

  • Enhanced image quality and durability in printed and copied documents.
  • Improved toner performance and reliability.
  • Accurate and reliable measurement of boron content on toner particle surfaces.


Original Abstract Submitted

A toner comprising a toner particle, the toner particle comprising a binder resin and a boric acid, wherein, where the toner particle is subjected to ATR-IR analysis by using germanium as an ATR crystal in an ATR method, a peak corresponding to the boric acid is detected, the toner comprises a fatty acid metal salt on a surface of the toner particle, and a presence ratio of an boron element on the surface of the toner particle is 0.01 atomic % or less as measured by X-ray photoelectron spectroscopy.
