Abstract
The present invention provides a method of preparing a toner for electrostatic charge image development comprising the steps of a liquid mixture preparation process for preparing a liquid mixture by mixing at least a resin particle dispersion prepared by dispersing resin particles in a solution including a dispersing agent having a polarity, and a coloring agent particle dispersion prepared by dispersing coloring agent particles in a solution including a dispersing agent having a polarity, an aggregated particle dispersion preparation process for preparing an aggregated particle dispersion by forming aggregated particles in the liquid mixture, and a fusion process for fusing the aggregated particles by heating, wherein the first dispersing agent and the second dispersing agent have the same polarity, a toner for electrostatic charge image development obtained by the method, an electrostatic charge image developer containing the toner and a carrier for electrophotography, and an image forming method comprising the steps of a process for forming an electrostatic latent image on an electrostatic latent image carrying member, a process for forming a toner image by developing the electr…
