ABSTRACT:
Image recording apparatus is disclosed in which a laser beam is modulated in accordance with a digital input which includes character information as well as the type of font and the point size. The modulated beam is scanned onto a photoconductive belt to form a latent electrostatic image, and the image is developed by a xerographic process. In order to produce a high-quality print of subject matter which includes a variety of fonts and point sizes, each font is exposed at a preselected level which provides the optimum exposure for that particular font.
