摘要： 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.

摘要： Disclosed is a toner for electrostatic linage development that has sufficient low-temperature fixability, can provide high post-fixing separability, and can be used for stable formation of images at high speed.The toner for electrostatic image development includes toner particles containing a binder resin. The binder resin contains as a part thereof a block copolymer having an A-B-A block copolymer structure including polymer blocks A composed of a structural unit derived from an alkyl methacrylate and a polymer block B composed of a structural unit derived from an alkyl acrylate. The glass transition point (TgA) of a homopolymer of the alkyl methacrylate forming the polymer blocks A is higher than the glass transition point (TgB) of a homopolymer of the alkyl acrylate forming the polymer block B.
