Method of manufacturing toner, the toner produced thereby, developer containing the toner and an image forming apparatus using the toner

摘要

A method of manufacturing a toner including dissolving or dispersing a toner component containing a colorant and a resin in an organic solvent to obtain a liquid solution or dispersion, continuously emulsifying and dispersing the liquid solution or dispersion in an aqueous medium containing a particulate dispersant to obtain emulsified primary particles, controlling cohesion and agglomeration of the emulsified primary particles and removing the organic solvent, such that the ratio (T 1 /T 2 ) of the arithmetic mean accumulation time (T 1 ) of the emulsified primary particles obtained in the controlling step to the arithmetic mean accumulation time (T 2 ) of the emulsified primary particles obtained in the continuously emulsifying and dispersing step is from 1 to 5.
