Abstract
The present invention discloses an ink-jet type recorder comprising reserving means for withholding a recording liquid consisting of a mixture of electroviscous liquids (EVL) and coloring materials, the reserving means including a plurality of nozzles from which a jet of the recording liquid spouts out, and a plurality of pairs of electrodes for impressing a voltage to the recording liquid withheld in the reserving means, wherein the impressed voltage to the plurality of pairs of electrodes is controlled in order to change the viscosity of EVL so that a jet of the recording liquid spouts out from the plurality of nozzles onto recording media. Also the present invention discloses an ink-jet type recorder comprising reserving means having an EVL withholding unit for withholding EVL and a recording liquid by way of two separate liquid phases contacting each other at one end, and a plurality of pairs of electrodes for impressing a voltage to EVL withheld in the reserving means, wherein the impressed voltage to the pairs of electrodes is controlled in order to change the volume of EVL so that EVL directly pumps out the recording liquid onto recording media through the plurality of nozzles.
