1. An image processing apparatus that generates binary data composing each of a plurality of divided images for completing an image with superimposing the plurality of divided images, which differ from each other in formation timing, said apparatus comprising:

  • an obtaining unit for obtaining a plurality of multi-valued data corresponding to the plurality of divided images for obtaining a plurality of binary data composing each of the plurality of divided images; and

    a generator for generating binary data composing each of areas located in same positions of the plurality of divided images shown by the plurality of multi-valued image data obtained by said obtaining unit, according to a dot arrangement order which is defined for L positions of a dot arrangement pattern for determining dots to be assigned to the L positions in each area,wherein said generator generates the binary data so that X (1≦

    X≦

    L) dots assigned in the area of each of the plurality of divided images that is formed at precedent formation timing are assigned to positions of the arrangement order of first to Xth, and generates the binary data so that Y (1≦

    Y≦

    L−

    X) dots assigned in the area of each of the plurality of divided images that is formed at subsequent formation timing are assigned to positions of the arrangement order of (X+1)th to (X+Y)th.
