  • Publication number: 20210096495
    Abstract: An image forming apparatus includes a density detector, a determination unit, and a change unit. The density detector detects a density of a patch image formed on an image carrier over plural places. The determination unit determines whether plural detection results of the density detector are within a threshold. When the number of determination results, by the determination unit, that the density of the patch image is not within the threshold exceeds a predetermined number, the change unit changes (i) a detection timing at which the patch image is detected by the density detector or (ii) a formation position of the patch image on the image carrier.

  • Patent number: 9878722
    Abstract: A monitoring device includes an estimation unit, a detection unit, and a correction unit. The estimation unit estimates a degree of degradation of a moving object based on at least an amount of movement of the moving object. The detection unit detects an environment state of the moving object at a time when the moving object is moved, as operation parameter values including an amount of an operation at a time when an operation unit is operated and an operation time. The correction unit corrects the degree of degradation, which is estimated by the estimation unit, based on the operation parameter values detected by the detection unit.
