ABSTRACT:
An image output apparatus which outputs a high quality image by using a small number of pixel clock generation units, for use with a printing engine which has a plurality of laser beam control units. The image output apparatus includes a plurality of output units which output video signals based on print data to the respective laser beam control units in synchronization with a clock signal; and a plurality of clock control units which are arranged in correspondence with respective groups, that are prepared by grouping the plurality of output units, so as to decrease an optical path difference between laser beams controlled by the corresponding laser beam control unit. Each of the clock control units generates the clock signal on the basis of a synchronizing signal generated in the printing engine, and outputs the generated clock signal to output units belonging to a corresponding group.
