Title:
静電荷像現像用トナー
Document Type and Number:
Japanese Patent JP7374693
Kind Code:
B2
Abstract:
To provide an electrostatic charge image developing toner excellent in low temperature fixability, image heat resistance and charge stability, and a method for manufacturing the same.SOLUTION: The electrostatic charge image developing toner comprises a binder resin including a crystalline polyester resin and a styrene acrylic resin and a colorant. A raw material monomer of 25 mol% or more and 40 mol% or less in the crystalline polyester resin is at least one kind of monovalent long-chain aliphatic monomers selected from a group consisting of a 10C or more and 22C or less aliphatic monocarboxylic acid based compound and 10C or more and 22C or less aliphatic mono alcohol, and the weight average molecular weights of the crystalline polyester is 2,000 or more and 5,000 or less. The method for manufacturing the electrostatic charge image developing toner includes the step of suspending and polymerizing a polymerizable monomer composition including a styrene acrylic resin raw material monomer, a crystalline polyester resin and a colorant in an aqueous medium.SELECTED DRAWING: None
