Patent ID: 7929177

Claim:
An image forming device comprising: an image generating section that generates an image based on input information; an image processing section that performs a grayscale screen process on the image generated by the image generating section and generates grayscale data and screen type information for each pixel of the image; a light intensity correction circuit that receives the grayscale data and the screen type information for each pixel of the image and that generates a light intensity correction value for a light emitting element corresponding to each pixel of the image based on information comprising the screen type information and a basic correction value; and a line head that receives for each line the grayscale data and the light intensity correction value of each light emitting element, from the light intensity correction circuit, and that exposes an image holding unit by emitting light from light emitting elements for each line of the grayscale data and light intensity correction values received so as to correct the intensity of each light emitting element of each line based on the screen type information and the grayscale data.
