Image forming apparatus

Image Number 14 for United States Patent #8447197.

An image forming apparatus, which appropriately performs a banding correction even if similar banding does not always occur at a same position of a recording medium, detects reflected light from a test patch image and obtains information on a density change caused by a periodically-uneven rotation of a rotation member, and performs a density correction at an arbitrary position of a print image based on the acquired information on the density change.
