PROBLEM TO BE SOLVED: To provide an abnormality contents storage device constituted so that a serviceman can surely find out the place of abnormality occurring in an image forming device, etc. SOLUTION: A CPU 50 always monitors the states of an optical system 2, an image forming system 3 and a fixing device 60 provided in a copying machine, to detect the abnormality occurring in each part. The CPU 50 reads out a service call corresponding to the contents of the detected abnormality from a service call table and stores the service call in the service call storage region of a nonvolatile RAM 53. Further, the count value of a paper counter P at this time is stored in the service call storage region. The service calls and paper count values by 10 times in the past can be stored in the service call storage region. Moreover, the nonvolatile RAM 53 is provided with a region used as a service call counter S for recording the number of the read-out times of the service call. The contents stored in the nonvolatile RAM 53 can be displayed on a display part 79 by the operation of the operating key of a control panel 70. |
