ABSTRACT:
In an ink jet system printer of the charge amplitude controlling type, it is required to ensure stable printing that viscosity and surface tension of ink liquid supplied to a nozzle is maintained at a constant value. To this end, there is provided a heat generating pipe in an ink supply system and a control circuit for controlling power supply to the heat generating pipe. The viscosity and surface tension of the ink liquid is maintained at a constant value by holding the ink liquid at a predetermined temperature.
