    摘要： A liquid developer is provided. The liquid developer includes a liquid insulator and toner particles. The liquid insulator toner particles include a resin material, a colorant, a substance A, a substance B, and a substance C. The substance A is an acrylic-modified silicone. The substance B is at least one selected from the group consisting a quaternary cationic silicone, an aminophenyl-modified silicone, and a phenyl-modified silicone. The substance C is at least one of a silanol-containing polysiloxane and a fluorine-modified silicone. The average degree of roundness R1 of the toner particles is 0.890 or greater, if the degree of roundness is expressed as L0/L1, where L1 (μm) is a circumference of a profile view of a measured particle and L0 (μm) is the circumference of a perfect circle of a circumference of a profile view corresponding to the profile view of the measured particle.

    摘要： A process for producing a toner for a liquid developer includes: preparing an emulsion liquid containing an aqueous dispersion medium and, dispersed therein, dispersoids containing a resin material which has an acidic group having a salt structure formed with a basic substance and has an acid value of from 5.0 to 20 mg KOH/mg when it is in a form of an acidic substance without forming a salt with the basic substance, a colorant and an organic solvent which dissolves the resin material; coalescing the dispersoids contained in the emulsion liquid to obtain coalescent particles; removing the organic solvent contained in the coalescent particles to obtain colored resin particles; washing the colored resin particles with an aqueous liquid (first washing step); dispersing the washed colored resin particles in an aqueous liquid and performing an acid treatment to obtain an acidic dispersion liquid having a hydrogen ion exponent (pH) adjusted to 3.0 to 6.0; washing the colored resin particles subjected to the acid treatment with an aqueous liquid (second washing step); and drying the colored resin particles subjected to the second washing step.

    摘要： A liquid developer is provided. The liquid developer comprises an insulation liquid, toner particles dispersed in the insulation liquid, a dispersant dissolved in the insulation liquid; and a charge control agent dissolved in the insulation liquid. The charge control agent is represented by the following chemical formula (I): wherein in the chemical formula (I) R1 represents an alkyl group or alkenyl group having a carbon number in the range of 8 to 22, and R2 represents a hydroxyalkyl group. The liquid developer has both superior dispersibility and a charge characteristic of toner particles. Further, an image forming apparatus is also provided.
