1. A color image forming apparatus comprising:

  • a semiconductor laser;

    a semiconductor laser modulation signal generating part generating a signal for modulating said semiconductor laser;

    a semiconductor laser driving part driving said semiconductor laser based one the semiconductor laser modulation signal;

    a scanning part scanning a photosensitive body with light output by said semiconductor laser; and

    a scanning light detecting part detecting the scanning light output by said semiconductor laser at a predetermined position, wherein;

    said color image forming apparatus produces a latent image on the photosensitive body based on a signal output from said scanning light detecting part in response to detection of the scanning light;

    said semiconductor laser modulation signal generating part comprises a clock generating part and a clock modulation part;

    said semiconductor laser and said semiconductor laser driving part are provided for each color of yellow, magenta, cyan and black; and

    further, a plurality of the semiconductor lasers are provided for at least one color of yellow, magenta, cyan and black.
