Abstract:
1. An image forming apparatus having functions of tilt adjustments to a mirror for reflecting a laser beam and outputting an image after registration of a plurality of images, the apparatus comprising: a laser source for generating laser beams; a plurality of mirrors for reflecting a plurality of light beams including at least one reference beam for forming the images based on the laser beams generated by the laser source; image forming means for forming the images for each of the light beams; image transfer means for storing the images formed by the image forming means and transferring the stored images in a predetermined sub-scanning direction; inclination detecting means for detecting inclinations of the images stored by the image transfer means in a main-scanning direction in relation to the sub-scanning direction at least on the reference beam; and inclination correcting means for correcting the inclinations detected by the inclination detecting means on the reference beam in the main-scanning direction by adjusting a relative angle of the mirror for reflecting the reference beam in the main-scanning direction.
