Abstract: An image forming apparatus, a color registration test pattern of the image forming apparatus, and a method of forming the color registration test pattern are provided. A time required for color registration may be reduced by minimizing a region in which a color registration test pattern is formed on an intermediate transfer body. A control method of the image forming apparatus, which includes photosensitive media arranged side by side to correspond to colors in a rotation direction of the intermediate transfer body, includes forming first patterns of the colors arranged in a single row in a sub-scanning direction in a first region of the intermediate transfer body over a single-rotation period of the photosensitive media, and forming second patterns of the colors arranged in a single row in the sub-scanning direction in a second region of the intermediate transfer body over another single-rotation period of the photosensitive media.
