Title:
TONER FOR ELECTROSTATIC CHARGE IMAGE DEVELOPMENT AND IMAGE FORMING METHOD
Document Type and Number:
Japanese Patent JP2018180172
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a toner for electrostatic charge image development that is excellent in heat-resistant storage property, can provide a sufficient fix level even when heating during fixing is reduced to avoid deformation and melting of a substrate for flexible packaging during printing on the substrate, and can provide an image having a toner image layer with sufficient substrate followability and folding resistance, and an image forming method.SOLUTION: A toner for electrostatic charge image development of the present invention is a toner for electrostatic charge image development that includes toner base particles containing at least a binder resin and an external additive, where the toner base particles each have a core-shell structure; the binder resin contains at least a styrene-acrylic resin and a polyvinyl acetate resin; 90 mass% or more of the polyvinyl acetate resin is present in a core part.SELECTED DRAWING: None
