摘要： PROBLEM TO BE SOLVED: To solve the problem that, if a spot of a consumable component to which a recording agent such as ink or toner adheres exists unevenly, the partial wear of the consumable component that contacts a certain region is remarkable in comparison with other portions thereof, and causes partial staining of paper to cause faulty printing, consequently, the consumable component must be exchanged, though its portion that contacts the other region is not worn so much, and is still in a usable state. SOLUTION: In the image forming apparatus, area to which the recording agent is made to adhere is measured by region of a recording medium, and when a cumulative value of the measured area exceeds a threshold, an image to be formed is reversed, whereby the worn spot of the consumable component is dispersed, and the exchange time of the consumable component is extended.

摘要： PROBLEM TO BE SOLVED: To make full use of the function of a member such as a photoreceptor or toner by setting the allowable level of an abnormal image for each user in detail, and also to optimally set a visit of a maintenance person. SOLUTION: An index value indicating a condition of the image forming apparatus is prepared from a multidimensional signal obtained by monitoring, and compared with a predetermined threshold value to predict a failure of the image forming apparatus which can occur in the near future. The types of abnormal images predicted to appear when the index value exceeds a second threshold value that is a predetermined level are specified based on the prediction of the occurrence of the failure. The abnormal image is falsely generated from the types of abnormal images specified by the second threshold value and printed and output. Then, a user views the output abnormal image, and judges whether the apparatus is continuously used as it is or whether the apparatus is replaced. COPYRIGHT: (C)2008,JPO&INPIT
