摘要： A developing device includes a container storing a two-component developer including a toner and a carrier, a toner carrying body carrying the toner in the container and supplying the toner to a predetermined image carrying body by rotation, a restricting member held in press contact with the toner carrying body, and a restricting nip section formed between the toner carrying body and the restricting member. The restricting nip section selects only the toner in the two-component developer to form a uniform toner layer on the toner carrying body.

摘要： 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.
