Abstract
An image forming apparatus supervising system includes a problem detecting device in each of image forming apparatuses, which detects a problem to be reported to a central control apparatus as a service person call when the problem occurs in the image forming apparatus. A first copysheet number storing device is employed to store a total number of copysheets having been copied before a current occurrence of the problem occurs in an image forming apparatus. A second copysheet number storing device is also employed to store a number of copysheets having been copied before a last occurrence of the problem. The problem is reported only when a difference between the numbers of copysheets stored in the first copysheet number storing device and the second copysheet number storing device exceeds a predetermined level so that an erroneously detected problem can be avoided from being reported as the service person call.
