摘要：
An ink composition contains a carrier medium and charged particles containing a coloring agent, which ink composition satisfies at least one condition of condition A or B: condition A that the specific charge quantity of the charged particles is in a range of 10 to 1,000 .mu.C/g with a positive or negative polarity; and condition B that the specific resistance of the ink composition is 10.sup.10 .OMEGA.cm or more; and ink-jet recording methods using the ink composition are proposed.
