Kind Code: A1 A method for producing a crystalline polyester dispersion having a narrow volume distribution with a volume average particle size of 0.2 to 1.0 μm useful as a toner, a dispersion obtained by the method, and image formation using the dispersion Toner, a developer using the toner, and an image forming method. A method for producing a crystalline polyester resin dispersion comprising the following steps (a), (b), and (c) in order. (A) a step of heating the crystalline polyester resin in an organic solvent to form a solution; (B) cooling the solution to deposit a crystalline polyester resin to obtain a coarse dispersion; (C) a step of further pulverizing the coarse dispersion with a mechanical pulverizer to obtain a dispersion having a volume average particle size of 0.2 μm to 1 μm; [Selection figure] None |
