Abstract

Liquid electrophotography apparatus including a plurality of members defining a flow path for a printing liquid. At least a first member of the plurality of members is arranged to generate an electric field. The liquid electrophotography apparatus also includes a first insulation layer arranged around at least a portion of a surface of the first member to prevent electrical discharge from the printing liquid.

Claims (10)

1. A method of forming solid conducive traces on a substrate, the method comprising:

forming a charged pattern on a first insulated roller, wherein an insulation on the first insulated roller comprises a photoresist, wherein the photoresist comprises an electrostatic image forming surface;

transferring a liquid containing a conductive solid to charged portions of the first insulated roller to form a liquid pattern on the first insulated roller;

fusing material of the liquid pattern;

transferring the fused material onto a substrate; and

solidifying the transferred, fused material on the substrate, where the solidified material is conductive.

2. The method of claim 1 , where the solidified material comprises carbon black.

3. The method of claim 1 , wherein the solidified material comprises a metal.

4. The method of claim 1 , wherein the solidified material comprises a semiconductor.

5. The method of claim 3 , wherein the substrate is a circuit board.
