PURPOSE:To prevent beforehand the printing quality from being deteriorated by inputting a detecting signal to a printing control part and stopping the device when an abnormality is generated in a heater driving part. CONSTITUTION:When an abnormality is generated in a heater driving part 1, a detecting signals Vs from an abnormality detecting part 2 is inputted to a printing control part 5 through a transfer mechanism part 4, and the control part 5 stops the device, and the abnormality contents are displayed on a display part 3. As for the mechanism part 4, the transfer to the mechanism part 4 from a photosensitive drum 6 is constituted of a brush system using a heater power source transfer brush A, an abnormality detecting signal transfer brush B, and a conductive plate C. |
