A long life developer is expected for printers and multifunction machines. Key factors of a long life developer are low contamination to carrier and durability of toner particles. Therefore the contamination ratio and durability of typical toner binder such as styrene/acrylic resin, polyester resin and COC resin were examined. Among three binders tested, COC resin showed least contamination ratio against carrier and excellent durability. This result suggests that COC resin toner has good potential for long life performance in dual component systems.
