ABSTRACT:
The present invention provides a method of producing a polymerized toner which removes a by-product microparticle generated as a by-product upon polymerization in a by-product microparticle removing step, efficiently obtains a wet colored resin particle which has low moisture content (wet cake) by decreasing clogs caused at filter element in a dewatering step, enhances a drying efficiency (shorten the drying time) in a drying step, has an excellent productivity and a printing ability.
