Abstract
The image forming apparatus includes a CPU that performs control to form an inspection image for determining whether or not banding is suppressed to be smaller than a predetermined threshold value; and a density sensor that detects an intensity of banding periodically occurring in a sub-scanning direction of the formed inspection image. If based the detected banding intensity, the CPU has determined that the banding is not suppressed to be smaller than the predetermined threshold value, the CPU performs control to not perform banding correction or performs control to re-set a relationship between a phase of a rotary member and correction information.
