Abstract
The present invention provides an improved process for producing organic particles (e.g. toner particles) having uniform charge controlling coating and excellent charge controlling effect. In the process, a dispersion comprising the organic particles (A), a specific compound (B) forming insoluble substances upon reacting with an insolubilizer (D) and a dispersing medium is prepared and then reacted with the insolubilizer (D).
