Abstract

Provided is a method of preparing a toner. The method includes preparing initial polymer latex, and aggregating solid particles, that is, polymer latex particles, included in the initial polymer latex, wherein the aggregating of the polymer latex particles includes adding at least some of the initial polymer latex and at least one type of cohesive agent into a reactor at a first temperature, quickly increasing the temperature of the reactor from the first temperature to a second temperature at a rate in a range of 2 to 20 ℃/min, and performing aggregation for a first period at the second temperature.
