| 发明名称 | Liquid developer and method for manufacturing the same | ||
| 摘要 | 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. | ||

| 主权项 | 1. A liquid developer comprising an insulating liquid and toner particles dispersed in said insulating liquid, wherein said 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, said second resin particles further contain a pigment and a dispersant for pigment, and in said liquid developer, solubility of said dispersant for pigment in said insulating liquid is not higher than 10 mass % at 25° C., wherein the first resin particles are discreet and independent from the second resin particles, and the first resin particles are attached to or cover the surfaces of the second resin particles by force of adsorption. | ||
