摘要： A toner comprises a first particle having a predetermined volume average diameter and including thermoplastic binding resin and a colorant mixed into the thermoplastic binding resin to apply a color thereto. Wax of a second particle whose volume average diameter is considerably smaller than that of the first particle, is attached to the first particle by mechanical pressure. A nonmagnetic particle of a third particle is attached to the wax. The volume average diameter of the third particle is considerably smaller than that of the second particle. The attachment of the nonmagnetic particle decreases the area of an exposed surface of the wax, thereby preventing the wax from being attached to other wax and preventing the wax from contacting another toner.
