Patent ID: 8173336

Claim:
A circuit pattern formation device using an electrophotographic system comprising: a photoreceptor provided with a dielectric thin film body on the surface thereof; a developing device for forming an electrostatic latent image pattern on the photoreceptor and for developing the electrostatic latent image pattern of a circuit pattern precursor using a conductive particle dispersed solution formed of dispersed electroconductive particles in a nonpolar solvent, wherein the electroconductive particles have particle diameters of 100 nm or less and adsorb ionic organic molecules on surfaces thereof; a liquid film removal unit for removing a liquid film of the nonpolar solvent of the conductive particle dispersed solution from the circuit pattern precursor developed on the photoreceptor; a liquid film application unit for forming the liquid film of the nonpolar solvent again on the circuit pattern precursor from which the liquid film has been removed; and a transfer unit for transferring the circuit pattern precursor having the liquid film of the nonpolar solvent again formed thereon to an objective substrate.
