Abstract
A toner set for electrostatic image development, includes: at least one kind of a colored toner that contains a coloring agent; and a transparent toner that does not substantially contain a coloring agent, wherein a proportion of particles having a shape factor of 0.94 or less in mother particles of the transparent toner is about 5% by number or less based on particles having a particle diameter of 7.5 to 15 μm, and a reflectance of the mother particles of the transparent toner is about 90% or more for light at a wavelength of 700 nm.
