ABSTRACT:
The present invention relates to toners for electrophotography wherein the main resin component comprises a lower molecular weight polymer and a higher molecular weight polymer each of which is different from the other wherein the higher molecular weight polymer has a glass transition point of at least 50.degree. C. and the lower molecular weight polymer has a glass transition point no higher than 65.degree. C. The above polymers comprise one or more polymers selected from styrene polymers, arcylic polymers, and styrene-acrylic copolymers. Generally, the lower molecular weight polymer has a weight average molecular weight of 50,000 or less and the higher molecular weight polymer has a weight average molecular weight of 80,000 or more.
