ABSTRACT:
A detector for detecting status quantities in processes of an image forming apparatus and a correction mechanism for changing parameters are connected to a controller. By virtue of this arrangement, the amount of current associated with a primary charging device in a latent-image process, the surface potential of a photoreceptor drum and a voltage correction coefficient are fed into the controller as status quantities. By using the entered status quantities as well as membership functions and fuzzy rules that have been stored in an internal memory of the controller, the controller executes fuzzy reasoning and outputs a signal indicating the failure rate or rate of erroneous setting of each processing element.
