Toner for electrostatic image developments |
摘要 |
Disclosed is a toner for electrostatic image 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. |
