摘要： An image forming apparatus includes a deterioration determining device to determine a deterioration degree of a latent image bearer based on a potential detected by a surface potential detector. The deterioration determining device calculates a relative value indicating the deterioration degree based on the aggregated number of pixels and a time value for each of virtually divided regions. The deterioration determining device determines a deterioration degree of a detecting target region of the virtually divided region based on a potential detected by the surface potential detector. The deterioration determining device further determines deterioration degrees of non-detecting target respective regions of the virtually divided regions based on the relative values of the non-detecting target respective regions, the relative value of the detecting target region, and the deterioration degree of the detecting target region.

摘要： An image forming system includes an image forming apparatus, a physical property detector, a data storage device, and a latent image carrier replacement time detector. The image forming apparatus includes a replaceable latent image carrier, forms a latent image on a surface of the latent image carrier, develops the latent image into a visible image, and transfers the visible image onto a recording medium. The physical property detector detects predetermined physical properties of the image forming apparatus in a continuous manner or an intermittent manner. The data storage device stores, as a specific physical property, data on at least one of the detected physical properties, which changes before and after replacement of the latent image carrier. The latent image carrier replacement time detector detects, on the basis of changes over time of the stored specific physical property, a latent image carrier replacement time.
