Abstract:
1. An image forming apparatus which has a light source for emitting a plurality of laser beams, forms a latent image on an image carrier with a plurality of laser beams emitted from the light source, and forms, onto a printing medium, an image developed on the image carrier, the apparatus comprising: measurement unit adapted to measure image densities of solid images formed simultaneously with respective combinations of (a1) a laser beam to be adjusted and (a2) each of other laser beams; and adjusting unit adapted to adjust a quantity of each of the plurality of laser beams so that an average of the image densities of the solid images formed by the respective combinations of (a1) the laser beam to be adjusted and (a2) each of the other laser beams matches a target density in accordance with a measurement result of said measurement unit.
