摘要： A maintenance system for image forming apparatuses, which make it possible to acquire appropriate maintenance information even when an exceptional trouble has occurred in an image forming apparatus, to thereby reduce maintenance time and maintenance costs. When an abnormal image occurs in an image forming apparatus connected to a host computer via a network, the image forming apparatus transmits image data of the abnormal image together with supplementary information. The host computer receives the abnormal image data and the supplementary information, and adds these to a database in an HDD. When a transmission request is received from the image forming apparatus, the host computer transmits abnormal image data and supplementary information stored in the HDD to the image forming apparatus. The image forming apparatus receives the abnormal image data and the supplementary information, and displays these on a display unit.

The apparatus has a rotating and moving electrophotographic photosensitive body. Successively along a rotating direction of the photosensitive body arranged are a first developing device using a two-component developing agent constituted of a magnetic carrier and a nonmagnetic toner and a second developing device using a one-component magnetic developing agent different in color from the nonmagnetic toner. The apparatus also has a control circuit for stopping an image forming operation when a trouble occurs in an apparatus body. To prevent the carrier of the first developing device from mixing in the second developing device, a drive mechanism is provided for detaching a magnet of the second developing device from the photosensitive body to a position at which the carrier adhering from the first developing device to the photosensitive body does not mix in the second developing device by means of a magnetic force of the second developing device when the image forming operation is stopped.

摘要： 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.
