18. An image analysis method executed by an information processing apparatus communicably connected to one or more image forming apparatuses each comprising: an image forming device that forms an image on a recording medium; an image reading device that reads the image to obtain read image data; and an image forming controller that executes a first inspection and detects in the read image data an image defect corresponding to a predetermined inspection item at a first cycle, the image analysis method comprising:
acquiring inspection source data based on the read image data obtained from at least one of the image forming apparatuses; and
executing a second inspection to inspect the inspection source data.
 
24. An image analysis method executed by an information processing apparatus communicably connected to a plurality of image forming apparatuses each comprising an image forming device that forms an image on a recording medium and an image reading device that reads the image to obtain read image data, the method comprising:
acquiring inspection source data based on the read image data obtained from at least one of the image forming apparatuses; and
detecting, on the inspection source data, image unevenness periodically occurring at a new cycle other than specific cycles of a predetermined inspection item including image unevenness, the new cycle commonly occurring in a plurality of pieces of the inspection source data based on read image data acquired from at least two of the image forming apparatuses.
