PROBLEM TO BE SOLVED: To make good of an ink supply, to move little against an impact and to avoid development of a leakage of an ink or the like by a method wherein a base member formed of a difficulty volatile fluid and/or a non volatile fluid and at least a particle with a specified average particle diameter are contained. SOLUTION: An ink back-flow avoiding body is used for a prevention of an ink leakage and at least contains a base member formed of a difficulty volatile fluid and/or a non volatile fluid and a particle, an average particle diameter of which is 10-20Oμm Further, a normally-known phthalic acid ester and the like is usually used as a base member for an ink back-flow avoiding body. All kinds of organic inorganic powders, a rubber, a calcium carbonate and the like are used as a particle for avoiding splashing of the ink back-flow avoiding body by an impact of dropping or the like as a base member. |
