IMAGE FORMING METHOD AND DEVICE THEREFOR

摘要

PURPOSE:To prevent an occurrence of a void in an image to obtain an ideal image while a cost and an image quality are kept favorable. CONSTITUTION:When an image in a low-coverage part is to be formed, in addition to the modulation of an exposure time of a laser beam, the laser beam is simultaneously modulated in intensity. The intensity of the laser beam at this time is so controlled as to be higher than that at the time of non-intensity modulation. A rate of change of a maximum energy density value of a latent image after an intensity modulation to an input coverage is so controlled as to be continuously changed.
