ABSTRACT:
A writing method is disclosed for an ink jet printer using an electro-rheological fluid wherein an electro-rheological fluid reservoir is provided in between static pressure tubes circuitously communicating with a larger-diameter portion and a smaller-diameter portion of a venturi tube. The pressure difference created in the venturi tube forces the injection of the electro-rheological fluid, and a writing potential is applied to the exit of the static pressure tubes from which the electro-rheological fluid is ejected so as to control the ejected amount.
