PROBLEM TO BE SOLVED: To provide a static charge image development toner capable of simultaneously realizing excellent low-temperature fixability and heat-resistant preservability, also with excellent image density of a printed matter, and a manufacturing method thereof.SOLUTION: A static charge image development toner has crystalline polyester (a) and an amorphous polyester (b) in a core part, and has amorphous polyester (c) in a shell part. The crystalline polyester (a) is crystalline polyester obtained by polycondensation of: an alcohol component including α,ω-alkanediol having 10-12 carbon atoms; and an acid component including a succinic acid having 10-12 carbon atoms in average. At least part of the amorphous polyester (b) is amorphous polyester obtained by polycondensation of alkylsuccinic acid having a branched alkyl group having 9-18 carbon atoms and/or an acid component including alkenylsuccinic acid having branch alkenyl group having 9-18 carbon atoms, and an alcohol component. A weight ratio ((a)/(b)) of the crystalline polyester (a) and the amorphous polyester (b) in the toner is 8/92-27/73. |
