ABSTRACT:
An ink jet device for an ink jet printer capable of minimizing the deterioration of the heat melted ink so as to produce printing having high stability and reliability. The ink heating temperature in the ink supply channel of the ink jet device is set to a lower temperature than the heating temperature in the ink jet part. Therefore, the heat melted ink is supplied into the ink jet part from the ink supply channel under a high viscosity but flowable condition. The heat melt ink is then supplied into the ink jet part where it is heated to a low viscosity condition so that it can be jetted.
