Abstract
The present invention provides a toner for developing an electrostatic charge image having excellent characteristics including a developing property, transfer property, fixing property, and cleaning property, and an efficient production method thereof. The present invention relates to a production method of a toner for developing an electrostatic charge image comprising: a first step of forming aggregative particles in a first dispersion including at least dispersed resin particles to prepare an aggregative particle dispersion, a second step of adding a fine particle dispersion containing dispersed fine particles into said aggregative particle dispersion and mixing therewith to form adhered particles having said fine particles adhering to said aggregative particles, and a third step of heating said adhered particles to be melted.
