Abstract
In order to realize edge smoothing in an image printing apparatus using a plurality of laser beams, commonality of a data processing circuit to the plurality of laser beams is attained by obtaining image data for the plurality of scanning lines in synchronism with a common scanning position of one of the plurality of laser beams and storing the image data into a common memory and generating laser modulating data for each of the laser beams; temporarily the laser modulating data for the other laser beams into FIFOS; using the laser modulating data in synchronism with the respective scanning positions of the plurality of laser beams to generate laser modulating signals for the respective laser beams in a PWM.
