Abstract: A toner including a mother toner comprising a binder resin and a calixarene having a halogen group, and a charge controlling agent having a halogen group that is present on a surface of the mother toner. The ratio of halogen ion to carbon ion on a surface of the toner is from 0.01 to 0.5, when determined by TOF-SIMS. The toner can be prepared by preparing a first liquid by dissolving or dispersing toner components including a calixarene having a halogen group and a binder resin and/or a precursor of the binder resin in an organic solvent; preparing a second liquid by emulsifying or dispersing the first liquid in an aqueous medium; removing the organic solvent from the second liquid; preparing a third liquid by washing the second liquid from which the organic solvent is removed; and adding a charge controlling agent having a halogen group to the third liquid.
