Claim Text:
1. An image processing apparatus for processing image data of a single color plane to be transmitted to an image forming unit configured to form an image of the single color plane by a first beam and a second beam, the apparatus comprising: an obtaining unit configured to obtain first information to be used for correcting a deviation in an image in a sub scanning direction due to a curve of a scanning line of the first beam and second information to be used for correcting a deviation in an image in the sub scanning direction due to a curve of a scanning line of the second beam; a setting unit configured to obtain a position in a main scanning direction for the first beam based on the obtained first information and a position in the main scanning direction for the second beam based on the obtained second information, and set, based on the obtained position for the first beam and the obtained position for the second beam, a common position in the main scanning direction, that exists in the middle between the obtained position for the first beam and the obtain position for the second beam, for the image data of the single color plane for each of the first beam and the second beam; and a correcting unit configured to shift, at the set common position in the main scanning direction, pixels included in the image data of the single color plane for each of the first beam and the second beam in the sub scanning direction.
