In an image display device in which two or more types of particles are sealed between a transparent substrate and a counter substrate, and the particles fly and move by Coulomb force or the like to display an image, the particles are sufficiently charged. An object of the present invention is to provide an image display particle and an apparatus method in which when an electric field is formed, the particle flies ideally and the contrast is sufficient and a good image is stably obtained. As the particles, there are used particles for image display, which are formed from base particles and child particles, and the child particles obtained by performing a surface treatment with a solution of a charge control agent are adhered to the surface of the base particles.
