TONER - A simplified explanation of the abstract

This abstract first appeared for US patent application 18479680 titled 'TONER

Simplified Explanation

The patent application describes a toner composition containing a binder resin and silica fine particles with specific characteristics. The total content of polyvalent metal elements in the toner particle, the particle diameter of the silica fine particles, and the solid Si-NMR measurements of the silica fine particles are all within defined ranges.

• The toner composition contains a binder resin and silica fine particles.
• The total content of polyvalent metal elements in the toner particle is between 0.10 to 2.50 μmol/g.
• The number-average particle diameter of the primary particle of the silica fine particle is 40 to 500 nm.
• Specific peaks in the DD/MAS measurement of solid Si-NMR of the silica fine particle are observed and their areas satisfy a defined ratio.
