PROBLEM TO BE SOLVED: To provide a liquid developer excellent in offset resistance and a method for efficiently manufacturing such a liquid developer. SOLUTION: The liquid developer contains toner particles dispersed in an insulating liquid, wherein the toner particles each have voids which communicate with the outer surface within the particle, the voids each have a portion whose diameter is larger than an open diameter in the vicinity of the outer surface of the toner particle within the void, and the toner particles hold the insulating liquid in the voids. When the open diameter of the void in the vicinity of the outer surface of the toner particle is represented by X [nm] and the maximum diameter within the void by Y [nm], a relationship of 0.01≤X/Y≤10 is satisfied.
