ELECTROSTATIC CHARGE IMAGE DEVELOPING TONER SET, ELECTROSTATIC CHARGE IMAGE DEVELOPER SET, TONER CARTRIDGE SET, PROCESS CARTRIDGE, IMAGE FORMING APPARATUS, AND IMAGE FORMING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18190076 titled 'ELECTROSTATIC CHARGE IMAGE DEVELOPING TONER SET, ELECTROSTATIC CHARGE IMAGE DEVELOPER SET, TONER CARTRIDGE SET, PROCESS CARTRIDGE, IMAGE FORMING APPARATUS, AND IMAGE FORMING METHOD

Simplified Explanation

The patent application describes an electrostatic charge image developing toner set that includes a white toner and a non-white color toner. The white toner particles contain a binder resin, a white colorant, and a release agent, while the color toner particles contain a binder resin, a color colorant, and a release agent. The relationship between the proportions of release agent present in the surface layer region of the white toner particles and the color toner particles is specified in the abstract.

• White toner and color toner particles in the set contain different components including binder resin, colorant, and release agent.
• The proportion of release agent in the surface layer region of the white toner particles is less than that in the color toner particles.

Potential Applications

This technology could be used in:

• Color printing
• Digital imaging

Problems Solved

• Improved color quality in printing
• Enhanced image development

Benefits

Original Abstract Submitted

An electrostatic charge image developing toner set contains a white toner that contains white toner particles including a binder resin, a white colorant, and a release agent, and a non-white color toner that contains color toner particles including a binder resin, a color colorant, and a release agent, in which, in observation of cross sections of the white toner particles and the color toner particles, in a case where a proportion of an area of a domain of a release agent present in a surface layer region from a surface of the white toner particles to a depth of 1 μm or less with respect to an area of all domains of the release agent present in a cross section of the white toner particles is represented by W, and a case where a proportion of an area of a domain of a release agent present in a surface layer region from a surface of the color toner particles to a depth of 1 μm or less with respect to an area of all domains of the release agent present in a cross section of the color toner particles is represented by W, a relationship of W<Wis satisfied.
