<p>PURPOSE:To maintain insulation property and simultaneously to attain the correspondence to reflection type sensor and a translucent type sensor by provid ing an electric device where a printing part is arranged in a carrying path from paper feeding to ejecting position in the image forming device with a printing pattern having the insulation property. CONSTITUTION:The printing pattern which has an insulating part X to the electric devices arranged in the carrying path from the paper feeding to ejecting position in the image forming device is provided on the printing part Y. Therefore, when on the way where action such as electrification, etc., is imparted from the printing side defective carry occurs in the image forming device and simultaneously the paper runs into an electrifier, current is leaked through the printing part Y. Thus, an accident such as the printing part being heated and smoking is prevented; additionally the printing part Y can correspond to the reflection type sensor and translucent type sensor in an optical jam detecting sensor arranged in the carrying path in the image forming device.</p> |
