Abstract
The present invention relates to an image forming process and an apparatus therefor for forming an image with liquid ink in response to output information from a facsimile or a computer, or optical information. In the present invention there is employed a screen member provided with a plurality of through holes and control electrodes respectively provided in the vicinity of said through holes, and voltages corresponding to the image information signals are applied to said control electrodes to selectively introduce electroconductive liquid ink into said through holes thereby forming an image, said image then being transferred onto or made to fly toward a recording material such as paper.
Claims7
An image forming process comprising:
- providing a screen member having plural through holes and provided with control electrodes in the vicinity of the respective through holes;
- providing a counter electrode opposite said screen member;
- maintaining the screen member in contact with conductive liquid ink;
- applying a predetermined voltage between the liquid ink and the counter electrode;
- and
- applying a voltage to the control electrodes in accordance with information signals to introduce the conductive liquid selectively into said holes thereby forming an image on said screen member.
