Disclosed is a toner for electrostatic image development that has low-temperature fixability and hot offset resistance and also has document offset resistance. The toner contains a hyperbranched polymer which is a homopolymer formed using an inimer having, in its molecule, a polymerizable functional group and a polymerization initiating group or is a copolymer formed using the inimer and a vinyl-based monomer. The hyperbranched polymer is preferably a terminal-modified hyperbranched polymer and is preferably obtained by a living radical polymerization process.
本发明公开了一种具有低温固定性和热偏移抗性以及文件偏移抗性的静电图像开发用色调剂。该色调剂包含一种高分支聚合物,该高分支聚合物是使用具有聚合功能基团和聚合引发基团的内酰胺形成的同聚物,或者是使用内酰胺和基于
乙烯的单体形成的共聚物。该高分支聚合物最好是末端修饰的高分支聚合物,并且最好是通过活性自由基聚合过程获得的。
