ABSTRACT:
A metal paper guide is disposed near the transcription section for leading a copy paper into the transcription section. The metal paper guide is grounded in the normal operational mode at the normal humidity condition. When the copying machine is placed in a high humidity condition, the metal paper guide is isolated from the grounded terminal for preventing the leakage of charges supplied on the copy paper through the metal paper guide.
