Steuerung der entwickelten Tonermenge unter Verwendung von Lasermodulationen von getrennten Unterelementen eines Bildes

摘要

A method and apparatus for developing a pixel in an image forming device (10) includes split developing the pixel using a split sub-pixel modulation technique (FIG. 3). Split development provides for at least two non immediately adjacent areas of the pixel to be developed more fully than an area in between the two non immediately adjacent areas. In the context of a laser printer, the laser is sub-pixel modulated at least twice (FIG. 2, signal C) upon the electrophotoconductive drum for selected pixels, thus effectuating a reduced discharge of the drum and reduced subsequent development of toner mass thereon. This controlled amount of developed toner mass reduces toner waste and toner scatter while maintaining image integrity.
