ABSTRACT:
An image forming solvent stored in a bottle is sent to a sub tank by a pump. The image forming solvent with the bubbles eliminated at a sub tank with the upper end open is filled into a jetting device having nozzle holes. The water level of the sub tank is kept constant by a discharge pipe communicating with the sub tank at a position lower than the jetting device. As a result, the inside of the jetting device is in a constant negative pressure state so that the atomized image forming solvent is jetted from the jetting device. At this time, the atomized image forming solvent can be jetted stably. The jetting state of the jetting device is not effected by the pulsation of the sub tank pump.
