摘要

In this study the impact of toner binder resin design, especially molecular weight and molecular weight distribution, on the fusing performance in oil-free hot roll fusing has been studied for the new class of environmentally friendly cyclic olefin copolymers (COC). The first results presented in this report indicate that the fusing latitude, or so-called anti-offset-window (AOW), in hot roll fusing is strongly influenced by the amount of longer chains in the underlying binder resins. Surprisingly, only the hot offset temperature increases with the amount of longer chains in the binder resin, whereas the cold offset temperature is not affected at all. In parallel with a larger AOW, the minimum temperature for acceptable fixing is increased slightly, and lower image gloss is obtained. More detailed studies on a variety of exemplary toner formulations are necessary to better understand the impact of binder resin design; Tg, Mn, Mw, molecular weight distribution, and elasticity effects on fusing performance need to be explored.
