Abstract
An image forming apparatus for rendering graphics objects in a frame memory, which includes a line memory for storing dot image data for each scan line of the graphics objects, a deciding unit that decides a position of a difference pixel having different values of corresponding pixels between the scan line stored in the line memory and a target scan line immediately thereafter, and a difference updating unit that, of the dot image data stored in the line memory, updates a value of the difference pixel decided by the deciding unit to the value of the pixel in the target scan line.
