TONER, DEVELOPER, TONER STORAGE UNIT, IMAGE FORMING APPARATUS, AND IMAGE FORMING METHOD
Document Type and Number:
Japanese Patent JP2022131656
Kind Code:
A
Abstract:
To provide a toner that can achieve both low temperature fixability and a heat-resistant storage property, and can prevent contamination of a cleaning member and a photoreceptor while maintaining a good cleaning property.SOLUTION: A toner of the present invention is a toner in which a surface of a toner base particle containing a binder resin, colorant, and wax is covered by resin fine particles. The resin fine particles each have a core-shell structure consisting of a shell part and a core part. The glass transition temperature TgA of the shell part is higher than the glass temperature TgB of the core part. When the toner is measured by a rheometer, the storage elastic modulus G'1 at 70°C during temperature increase is 1.0×105 Pa or more and 1.0×106 Pa or less, and the storage elastic modulus G'2 at 100°C during temperature increase is 1.0×104 Pa or more and 5.0×104 Pa or less.SELECTED DRAWING: Figure 1
