Benefits:

• Improved print quality.
• Enhanced durability of printed materials.
• Consistent performance of toner cartridges.

Commercial Applications: Optimizing Toner Composition for Enhanced Print Quality and Durability

Prior Art: Research on toner composition and element distribution in toner particles.

Frequently Updated Research: Ongoing studies on toner materials and composition for improved printing technology.

Questions about Toner Composition: 1. How does the unique element distribution profile in toner particles impact print quality? 2. What are the potential implications of optimizing inorganic element concentration in toner for commercial printing applications?

Original Abstract Submitted

A toner includes toner particles containing a binder resin, a colorant, and inorganic fine particles, in which in a depth profile of an element distribution in a depth region from the outermost surface of a particle to a depth of 500 nm the depth profile being obtained by an element analysis performed by X-ray photoelectron spectroscopy using the toner as a sample, two or more minimum points of a concentration of a carbon element in the depth region exist, a concentration of an inorganic element becomes a maximum value at a depth position corresponding to each of the minimum points, and the inorganic element is an element derived from the inorganic fine particle.
