PURPOSE:To continuously form a stable and satisfactory image by incorporating nonhygroscopic solvent as liquid dispersing medium. CONSTITUTION:Liquid dispersing medium containing crosslinking structure substance for holding the medium to control adhesive properties by conduction includes nonhygroscopic organic solvent. The organic solvent which satisfies nonhygroscopic and nondrying conditions includes, for example, triacetin. The content of the organic solvent is 10-60% to total amount of ink. However, it contains hygroscopic solvent for obtaining adhesive controllability by conduction as liquid dispersing medium in addition of the organic solvent. The hygroscopic solvent includes, for example, methyl alcohol, ethyl alcohol, n-propylene alcohol, isopropylene alcohol, etc. The crosslinking structure substance includes, for example, vinylalcohol-vinyl acetate copolymer having 10 to 70mol% of saponification value. The copolymer can desirably hold the nonabsorptive solvent. |
