Abstract
An image recording apparatus includes a reference clock signal generating unit which generates a reference clock signal; a light beam generating unit which generates a plurality of light beams; a beam detect sensor which detects the plurality of generated light beams to output a plurality of light beam detection signals; an image clock signal. generating unit responding to the reference clock signal and the plurality of light beam detection signals to successively generate a plurality of image clock signals. These clock signals have the same period, and correspond to the plurality of light beam detection signals. Additionally, included is a modulating unit responsive to the plurality of image clock signals to modulate the generated plurality of light beams based on the plurality of image data; a driving circuit which drives the light beam generating unit based on the plurality of modulated light beams; a light beam scanning unit which performs a period scan on a photoreceptor with the plurality of generated light beams; and an image recording unit that records an image based on the plurality of light beams used to scan the photoreceptor.
