Abstract: In a liquid developer in which toner particles are dispersed in an insulating liquid, the toner particles have a core-shell structure that first resin particles containing a first resin are attached to or cover surfaces of second resin particles containing a second resin. The second resin particles further contain a pigment and a dispersant for pigment, and solubility of the dispersant for pigment in the insulating liquid is not higher than 10 mass % at 25° C.

Abstract: A liquid developer includes an insulating liquid and a plurality of toner particles. The plurality of toner particles has a volume-based median size not smaller than 0.5 μm and not greater than 3 μm as a whole, and a volume-based coefficient of variation not lower than 40% and not higher than 130%. The plurality of toner particles includes a first toner particle group of the toner particles having a particle size not greater than 1 μm. The number of toner particles constituting the first toner particle group occupies not lower than 20% of the total number of toner particles. The toner particles in the first toner particle group have an average circularity not smaller than 0.945.
