Toner for electrostatic charge image development and manufacturing method thereof, and electrostatic charge image developer, toner cartridge, process cartridge and image forming apparatus

Abstract

There is provided a toner for electrostatic charge image development, which includes a binder resin that includes a non-crystalline polyester resin and a crystalline polyester resin, and a colorant, wherein in a measurement of an acetone-soluble fraction of the toner by gel permeation chromatography, in which W1 represents the total area of an elution curve of the acetone-soluble fraction, F(0-10) represents an eluate corresponding to from the beginning of the elution to 10% elution of W1 over time, and F (80-100) represents an eluate corresponding to from 80% elution to 100% elution of W1 over time, the amount of an aliphatic unsaturated dicarboxylic acid-derived component of the resins contained in the eluate F(0-10) is in the range of from about 0 mol % to about 10 mol % relative to the total amount of the acid-derived components of the resins contained in the eluate F(0-10), and the amount of the aliphatic unsaturated dicarboxylic acid-derived component of the resins contained in the eluate F(80-100) is in the range of from about 20 mol % to about 60 mol % relative to the total amount of the acid-derived components of the resins contained in the eluate F(80-100).
