Title:
TONER FOR ELECTROSTATIC CHARGE IMAGE DEVELOPMENT, AND METHOD FOR PRODUCING TONER FOR ELECTROSTATIC CHARGE IMAGE DEVELOPMENT
Document Type and Number:
Japanese Patent JP2011145321
Kind Code:
A
Abstract:
To provide a toner for electrostatic charge image development (hereinafter referred to as the toner) having superior low temperature fixability and high transfer efficiency, even in a high temperature and high humidity environment, and giving a printed image of high density, and to provide a method of producing the toner.
The toner for electrostatic charge image development is obtained by aggregating and melt-sticking, in an aqueous medium, resin particles (A) comprising a resin obtained by polymerizing at least a vinyl-based monomer dispersed with an anionic surfactant, resin particles (B) comprising a polyester resin dispersed with an anionic surfactant, and a colorant dispersed with an amphoteric surfactant.
