Abstract
It is possible for the present invention to carry out the inclination correcting by adding a simple constitution of shifting an image only in the main-scanning direction to that of the conventional image processing apparatus. The first line shifting means 65 shifts the image data in the main scanning direction by specific number of lines in the shifting amount corresponding to the inclined angle detected by the inclined angle detecting means 66. The first rotating means 85 rotates the image data stored in the first image memory 88 by 90 degree or 270 degree, and then interchanges the main-scanning direction and the sub-scanning direction. The second line shifting means 91 shifts the image data rotated by the first rotating means 85 in the main-scanning direction.
