PROBLEM TO BE SOLVED: To provide a liquid developing agent which has a melting point at 40°C or higher and at a fixing temperature or lower as a solid plasticizer to plasticize a binding resin contained in toner particles, and is dissolved in a carrier liquid at the melting point or higher but is not dissolved in the carrier solution below the melting point, and suppresses the set-off of an image compared with such a case that the solid plasticizer is not used.SOLUTION: The liquid developing agent includes: the toner particles containing a colorant, the binding resin, and the solid plasticizer plasticizing the binding resin; and an insulating carrier liquid. The solid plasticizer which has the melting point of 40°C or higher to the fixing temperature or lower is dissolved in the carrier liquid at the melting point or higher but is not dissolved in the carrier liquid below the melting point. |
