PROBLEM TO BE SOLVED: To make it possible to receive information from a remote place even under abnormal condition by parking a received image to an image accumulating means, then displaying a message 'print out unexecutable' and printing out if an abnormality is eliminated, when the abnormality is detected in an image formation process under a print out state. SOLUTION: A first - third high voltage output abnormality detecting circuits 4-6 connect an abnormality detection signal to a controller 15, if a target value is not reached. This abnormal state means the cutting of a charged wire in a primary electric charger 9 and a transfer electric charger 11, the faulty circuit parts for each of high voltage power supplies 1-3, a leakage near the primary electric charger 9 and the transfer electric charger 11 and the abnormal action of a control signal which is output from the output terminal a, d, f of the controller 15. The controller 15 stores the contents accumulated in an image buffer memory 16 and displays a warning message to indicate the presence of an abnormal output to the display panel of an operating part 18. |
