Title:
静電荷像現像用トナー
Document Type and Number:
Japanese Patent JP7198639
Kind Code:
B2
Abstract:
To provide an electrostatic image developing toner which is excellent in low-temperature fixability and preservability and furthermore materializes printed matter excellent in image density.SOLUTION: The electrostatic image developing toner is provided that contains a core and a toner particle of a core shell structure. The core contains: a styrene-based resin (AS); and a crystalline resin (C) which is a polycondensation product of an alcohol component (C-al) including a specific amount of a 1,6-hexanediol and a carboxylic acid component (C-ac) including a specific amount of an aliphatic dicarboxylic acid compound having 12 to 16 carbon atoms. A shell contains an amorphous composite resin (AH) including: a specific polyester segment (AH-1) which is a polycondensation portion of the alcohol component (A-al) including an alkylene oxide adduct of bisphenol A and a carboxylic acid component (A-ac) including a specific amount of succinic acid; and a vinyl resin segment (AH-2) which is an addition polymerization portion of a monomer component (A-st) including the styrene-based resin.SELECTED DRAWING: None
