The Effects of Crystalline Polyester on Toner Properties
  DOI :  10.2352/J.ImagingSci.Technol.2004.48.5.art00006  Published OnlineSeptember 2004

The regulation of energy consumption for printers and copiers is becoming increasingly strict each year. Also, with increasing speeds of the machine system, the fusing of toner on paper becomes even more difficult. Thus, toner that fuses at lower energy is expected. There are several solutions to address this issue. A typical method is to use low Tg and low Tm resins for binder. This solution, however, offers limited improvement. Crystalline polyester (CPES) is a long studied candidate that shows great promise. However CPES is not yet widely used due to its poor storage stability and low anti-offset properties. This report explains how to overcome problems encountered with toner containing CPES, improved uses of CPES in toner, and the enhanced properties of CPES. The properties of toner containing CPES, and how that toner works for low energy fusing, are described.
