Abstract

To provide an emulsion polymerized agglomerated toner for electrostatic charge image which is excellent in the fixing property even at a high temperature without deteriorating other properties and which does not emit an odor offensive to people, and a process for its production. An emulsion polymerized agglomerated toner characterized in that the odor index of aliphatic aldehydes measured by gas chromatography is at most 300, and an emulsion polymerized agglomerated toner which is an emulsion polymerized agglomerated toner obtainable via a polymerization step, a flocculation step and an aging step, characterized in that an emulsion polymerized latex before the flocculation step is a latex having a peroxide value of at most 30.
