摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus of a liquid droplet ejecting type which can surely discharge mixed air bubbles and can form a stable image.
SOLUTION: A negative pressure of a sub tank 35 is detected. If the value is lower than a specified value, the ink is extracted by a pump 115 so that the sub tank 35 and a recording head 34 have negative pressures. The sent ink is stopped by a second backflow preventing means 203 and reserved in a second liquid containing means 201. The second liquid containing means 201 is pressurized as the ink is stored therein. When the ink is filled into the sub tank 35 again, the liquid is sent with priority from the second liquid containing means 201. The ink is prevented from being accumulatively collected in the second liquid containing means 201 every time the ink is extracted from the recording head 34 and sub tank 35. There is no need of making the second liquid containing means 201 unnecessarily large, so that the recording apparatus can be made smaller.
