TONER - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240264545 titled 'TONER
The patent application aims to provide a toner that is less likely to cause image defects due to the detachment of silica aggregated particles, even after prolonged use in low-temperature and low-humidity environments.
- Toner includes a toner particle with a binder resin and a silica aggregated particle.
- Toner particle shows fragment peaks from boron atoms and boron-oxygen structures in TOF-SIMS measurement.
- Silica aggregated particle is made up of silica fine particles with specific size and aspect ratio.
Potential Applications: - Printing industry for high-quality image reproduction. - Photocopiers and laser printers for improved toner performance.
Problems Solved: - Reduced image defects in toner due to silica particle detachment. - Enhanced longevity and performance of toner in challenging environments.
Benefits: - Consistent image quality over extended periods. - Increased reliability of printing equipment. - Cost savings from reduced need for maintenance and replacements.
Commercial Applications: Title: "Advanced Toner Technology for Enhanced Printing Performance" This technology can be utilized in various printing devices, such as laser printers, photocopiers, and multifunction printers, to improve print quality and longevity.
Questions about the technology: 1. How does the presence of boron atoms and boron-oxygen structures in the toner particle contribute to its performance?
- The presence of these elements may enhance the adhesion properties of the toner, reducing the likelihood of silica particle detachment.
2. What specific benefits does the silica aggregated particle size and aspect ratio provide to the toner's performance?
- The size and aspect ratio of the silica aggregated particle may contribute to improved flow properties and reduced aggregation, leading to better image quality.
Original Abstract Submitted
to provide a toner that is less likely to cause image defects due to the detachment of the silica aggregated particle even when having been used for a long period of time in a low-temperature and low-humidity environment. the toner includes: a toner particle containing a binder resin; and a silica aggregated particle, wherein, in tof-sims measurement of the toner particle, a fragment peak derived from a boron atom and a fragment peak derived from a boron-oxygen structure are detected; the silica aggregated particle is an aggregated particle of silica fine particles having a primary particle size based on number of from 20 to 75 nm, a maximum feret's diameter of the silica aggregated particle is from 110 to 500 nm, and an aspect ratio thereof is from 1.50 to 4.00.
