Latest Developments in Toner Technology

摘要

Increasing number of xerographic printers are now utilizing chemically prepared toners as marking particles. There are various methods of making chemically prepared toners and each method had its own advantages and disadvantages. In general, the chemically prepared toners can be produced to a much smaller particle size than the conventional melt-pulverized toners. Further, it is possible to impart some unique and specific properties to chemical toners to aid with the simplification of electrophotographic process. In the meantime, progress is being continuously made with the manufacturing processes used in the production of conventional toner by melt compounding and pulverizing methods. Both approaches of manufacturing face tough challenges as they attempt to deliver marking particles that must meet the new printer requirements in future products. A comparison between the two technologies is made along with the hurdles that each must overcome in order to be successful.
