A method of forming registration marks and an image forming apparatus are provided. The registration mark includes two first patterns and one second pattern on an image carrier. The method includes: forming two first patterns on the image carrier; and forming a second pattern on the image carrier between the two first patterns. A specular reflection component in a light reflected by the second pattern is less than a specular reflection component in a light reflected by the image carrier. A diffuse reflection component in a light reflected by the second pattern is less than a diffuse reflection component in a light reflected by the first pattern.
