Abstract:
An image forming method comprising the steps of:reading an image signal in units of pixels; generating a first driving signal corresponding to an image portion and a non-image portion in one pixel based on the read image signal of each pixel; generating a second driving signal for clustering non-image portions of a plurality of pixels, on the basis of the read image signal of each pixel and an image signal of a peripheral pixel; detecting whether the read image signal of each pixel has a density not less than a predetermined density; selectively outputting the first driving signal if the image signal of the detected pixel has a density not less than the predetermined density; selectively outputting the second driving signal if the image signal of the detected pixel has a density not more than the predetermined density; outputting a laser beam on the basis of the selectively output first or second driving signal; forming a latent image on a photosensitive body with the laser beam; and forming an image by developing the formed latent image with toner.
