Binder resin used in a toner |
摘要 |
A toner for developing electrostatic images contains a binder resin and a colorant or a magnetic material. The binder is prepared by polymerizing ethylenically unsaturated monomer(s) in the presence of less than 0.1% by weight of the monomer(s) of a radical polymerization initiator. The resulting polymer or copolymer is dissolved in a polymerizable monomer and solution or suspension polymerized with a radical polymerization initiator. The resulting binder resin is substantially free of fragments of radical polymerization initiator which tend to bond to molecular chain terminals.
