Abstract
A pattern forming unit forms a color-misalignment detection pattern on an image carrier. A light-intensity detecting unit detects the color-misalignment detection pattern formed on the image carrier by irradiating the image carrier with a light and detecting light intensity of a reflected light from the image carrier. A color-misalignment-amount detecting unit detects an amount of a color misalignment of an image based on the light intensity of the reflected light detected by the light-intensity detecting unit. A spot of the light on the image carrier is elongated in a main-scanning direction.
