Patent ID: 7736830

Claim:
A method for forming a circuit pattern, comprising: a first step of forming by electrophotography a first toner image on a surface using a first toner, and a second toner image on the surface using a second toner, the first toner containing a resistive material, the second toner having a resistance different from that of the first toner; and a second step of transferring and fixing the first toner image and the second toner image from the surface to an object to be printed to form the circuit pattern; wherein the first toner is a conductor-containing toner having resistor particles coated with a resin layer; and the second toner is a glass-containing toner having glass particles coated with a resin layer; or wherein the first toner is a toner for forming a low-resistance pattern having resistor particles, glass frit disposed on the surface of the resistor particles, and a resin layer disposed around the resistor particles, and the second toner is a toner for forming a high-resistance pattern having resistor particles, glass frit disposed on the surface of the resistor particles, and a resin layer disposed around the resistor particles, the amount of the glass frit in the second toner being larger than that in the first toner.
