Abstract

Disclosed are toner compositions with low melt viscosity characteristics at relatively high glass transition temperatures, which compositions are particularly useful, for example, in xerographic flash fusing processes. The aforementioned compositions are comprised of a major amount of polymers with low melt viscosities, and unacceptable low glass transition temperatures such as bisphenol A-diethylene glycol copolycarbonate; a second rigid polymer such as bisphenol A-polycarbonate in an amount of 1 percent by weight with a macromolecular structure, and a higher glass transition temperatrue.
