摘要： A liquid developer capable of preventing each of the disadvantages of uneven development density caused by uneven distribution of colored particles, poor transfer due to an insufficient amount of the liquid, and poor fixing due to an excess amount of the liquid, without complicating handling with the generation of volatile gas. Present on the surface of toner particles to be dispersed in a carrier liquid made of dimethyl silicone are a silicone group of one-end methacryloxy-modified silicone and a basic group. The silicone group prevents agglutination of the toner particles with each other. The silicone group functions as an affinity group and provides the toner particles with an affinity to the carrier liquid. Thus, it becomes possible to disperse the toner particles uniformly in the carrier liquid. Besides, the basic group on the surface of toner particles allows the toner particles to ensure the desired charge amount. Therefore, colored particles such as the toner particles hardly agglutinate with each other in a nonpolar insulating liquid to be provided as a nonaqueous solvent, while the colored particles can be electrophoresed at high speed by an electric field.

摘要： An attriter which applies a strong stress to a liquid developer, sufficient for generating the chemically non-equilibrium state therein, is parallel-connected with a developing unit, so that the stress is applied to a part of the liquid developer carried from a storage tank to a developing tank. However, in order to suppress crushing of the toner due to the application of excessive stress, the operation of the attriter is controlled in the following manner. That is, a charge quantity detection unit which detects the toner charge quantity of the liquid developer in the developing tank is provided, and based on the detection result thereof, the attriter is controlled.
