A toner composition includes toner particles containing a resin; an optional wax; and an optional colorant, wherein the resin is a three latex system including a latex core, a latex shell, and a latex gel; and a glass transition temperature Tg of the latex core is lower than a glass transition temperature Tg of the latex shell. A method of making a toner composition includes blending a latex core resin including a base polymer and a latex gel and optional additives; adding a coagulant and an acid; homogenizing the slurry; raising the temperature to a value close to the glass transition temperature of the latex core resin while stirring to form aggregated particles having a size of from about 3 to about 9 μm; adding a latex shell resin to the slurry at a controlled rate to form a batch containing toner particles having a core and a shell; adding a pH adjustment agent to the batch to freeze growth of the toner particles; coalescing the batch by increasing the temperature to a coalescence temperature that is above a glass transition temperature of the shell; monitoring the batch for particle circularity; and recovering the toner particles.
