Abstract
A toner including core particles containing at least a resin and a colorant and coated with a resin coating layer is provided. The core particles are formed by flocculating and fusion-bonding at least resin microparticles and colorant microparticles dispersed in fluid dispersion, while two or more coating layers are formed over the core particles. A wax is added to at least one of the coating layer(s) but for the outermost coating layer, and the core particles. A ratio d/r between an average thickness d of the overall coating layers and a volume average particle size r of the core particles is adjusted to 0.01 to 0.6.
