ABSTRACT:
An image writing apparatus has improved performance of image reproduction based on a multi-beam scanning optical system, in which the number of laser beams n and the spacing of scanning lines p meet the condition: 1/(n.multidot.p).gtoreq.4 line pairs per millimeter. The optical system is further designed such that the number of deflection planes q of the deflector, a natural number m, where the period of repetitive patterns of image in the slow scan direction is equal to p multiplied by m, and the least common multiple E of m and n, or the least common multiple G of m, n and q meet the condition:
