ABSTRACT:
An object of this invention is to provide an image processing apparatus capable of preventing any color misregistration in printing even when the image processing apparatus is divided into a plurality of semiconductor integrated circuits. An image processing apparatus is used for an image forming apparatus for sequentially printing image processing results of color components by a plurality of photosensitive drums separated by predetermined distances in correspondence with the colors. In the image processing apparatus, a plurality of image processing sections for the respective color components are divided into a plurality of semiconductor integrated circuits. At least two of the plurality of image processing sections have storage sections which adjust the printing timings of the color components corresponding to the distances between the photosensitive drums. The image processing apparatus includes a synchronization circuit which synchronizes, with an image processing clock for image processing, a print request signal from a printer controller. The print request signal synchronized by the synchronization circuit is commonly used to adjust the read timings of the storage sections of the plurality of image processing sections.
