PROBLEM TO BE SOLVED: To provide an inkjet printer capable of ejecting an ink dot of a fixed size stably over a long term without requiring any cleaning. SOLUTION: Ink is circulated through an ink circulation path 10 and an ink tank 8 is provided with a stirrer 11 in order to sustain a constant dispersion mixing ratio of ink components. The ink tank 8 is also provided with a temperature regulator 12 and a temperature regulator 13 is provided in the vicinity of an ink chamber 7 in order to sustain the temperature of ink 3 at a constant level. An ink dot 14 of a fixed size can be ejected stably over a long term by sustaining constant surface tension and viscosity of ink 3 at an ejection opening 4. COPYRIGHT: (C)2004,JPO |
