ABSTRACT:
An image forming device includes an image generating section that generates an image including a plurality of screen types, an image processing section that performs a grayscale screen process on the image and generates grayscale data and screen type data for each pixel, a line head to which the grayscale data for each pixel section is sequentially transmitted, and a light intensity correction circuit that corrects light intensity of each pixel. The image processing section transmits the screen type data for each pixel to the light intensity correction circuit. The light intensity correction circuit transmits a light intensity correction value for each pixel to the line head. The light intensity correction value for each pixel is obtained based on the corresponding screen type data so that pixels of different screen types of the image are corrected in accordance with the corresponding screen types.
