Abstract:
1. A toner for developing latent electrostatic images, comprising: base particles including a colorant and a resin, and hard fine particles, wherein the hard fine particles exist on a surface of the base particles, protruding portions formed of fine organic resin particles which are different in composition from a resin contained as a main component in the base particles are provided on surfaces of the base particles, the main component in the base particles is a polyester resin and the fine organic resin particles are vinyl series resin, wherein the toner is obtained by forming a liquid droplet by dispersing an oil phase, which is produced by dissolving or dispersing a toner material including polyester resin in an organic medium, in an aqueous medium comprising fine organic resin particles forming the protruding portions, wherein a volume average diameter of the toner Dv is 2 μm to 7 μm, and a primary diameter of the fine organic resin particle is 520 nm to 710 nm.
