In an image forming apparatus, an image is formed pixel by pixel for each image data on a photoreceptor, wherein each pixel has a maximum recording width. A plurality of light emitting elements are aligned in an array form and each light emitting element is mounted with a setting width, wherein each light emitting element has a mount-shaped light amount distribution curve in which light amount data spread to both sides of a peak corresponding to the maximum light amount. Each pixel is divided into plural small pixels. Each small pixel is provided with a light emitting element so that an image is formed in the maximum recording width of each pixel by plural neighboring light emitting elements in accordance with image data of each pixel, wherein the image forming width at the light amount of 50% of the maximum light amount of each light emitting element is wider than the setting width of the light emitting element and is narrower than the maximum recording width of each pixel.
