Abstract

A toner composition is provided wherein by adding aliphatic lower molecular weight compounds which are partly or completely compatible with the binder resin(s), the melt viscosity of the toner composition can be lowered while the glass transition temperature (Tg) is more or less constant. Inclusion of these adding aliphatic lower molecular weight compounds, having a number average molecular weight, as measured by GPC in toluene, of from 500 to 3,000, results in toner compositions with a better adhesion and gloss and still an acceptable level of FOT and hot-offset. Also provide is a method for fixing toner images on a substrate.
