    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 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.
