摘要： A color synchronization method and a color laser printer form a color image by forming an electrostatic latent image on a photosensitive body using a laser scanning unit, developing the electrostatic latent image, and transferring the developed image onto a transfer belt. The printer includes a light source which radiates light, a timing belt which rotates the photosensitive body, a plurality of timing displays, which are provided on the timing belt at a constant interval, and on which the light radiated from the light source is incident, and a light receiving portion which detects the light reflected or transmitted by the timing displays. Synchronization for each color is controlled in response to a signal received by the light receiving portion.
