ABSTRACT:
Methods are described for rendering toner particles that are capable of being sufficiently and uniformly charged. The particles may be positively chargeable, non-magnetic, single component toner particles. At least one production method includes emulsifying a charge-controlling agent formed of a synthetic resin in an aqueous medium, the charge-controlling agent having been dissolved in or swollen with an organic solvent; removing the organic solvent; mixing with a suspension of toner base particles containing a binder and a colorant; and heating to fix the charge-controlling agent on the surfaces of the toner base particles. According to at least one method, a positively chargeable non-magnetic single component toner can be produced such that the amount of the charge-controlling agent deposited on the surfaces of the toner base particles falls within a range of 0.2 to 3.0 wt. %, with respect to the total weight of the toner.
