Abstract:
A toner composition includes low and high molecular weight polyester resins. It also includes a release agent, such as a polyolefin wax, and a tri-block copolymer having a structure of the form A-b-B-b-A, wherein A is a hard block and B is a soft block. The hard block is styrene, while the soft block is butadiene/butylene. Upon partial hydrogenation, the copolymer provides improved dispersion, mobility control, and domain size of the release agent.
