Claims9
A method of preparing toner, the method comprising:
- mixing a polyester resin dispersion, a colorant dispersion, and a wax dispersion;
- aggregating toner particles by adding a agglomerating agent to the mixed solution;
- and
- fusing the aggregated toner particles,
- wherein the polyester resin has a number-average molecular weight ranging from about 4,000 to about 7,000, a weight-average molecular weight ranging from about 18,000 to about 30,000, a peak molecular weight (Mp) ranging from about 4,000 to about 10,000, a polydispersity index (PDI) ranging from about 2 to about 5, and an acid value ranging from about 10 mg KOH/g to about 14 mg KOH/g.
