Abstract
A toner for electrostatic latent image development is comprised toner particles containing toner core particle containing at least a binder resin and a shell layer coating the toner core particle. The shell layer is smoothened to a predetermined level. And, when cross-sections of the toner particles are observed using a transmission electron microscope, cracks approximately perpendicular to surfaces of the toner core particles are observable inside the shell layer.
