Abstract
A method for forming circuit patterns having different resistances. The method includes (1) a first step of forming a first toner image using a first toner and a second toner image using a second toner, each by electrophotography, the first toner containing a resistive material, the second toner having a resistance different from that of the first toner; and (2) a second step of transferring and fixing the first toner image and the second toner image to an object to be printed such as a ceramic green sheet, to form a circuit pattern.
Claims12
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.
