Abstract:
1. An image processing apparatus which is used for an image forming apparatus for executing image processing for each of plural color components and sequentially printing image processing results of the color components by a plurality of photosensitive drums separated by predetermined distances in a conveyance direction of a printing medium in correspondence with the color components and in which a plurality of image processing sections which execute image processing for respective ones of the color components are divided into a plurality of semiconductor integrated circuits, wherein at least two of the plurality of image processing sections have storage sections, said storage sections adjusting printing timings of the color components corresponding to the distances between the photosensitive drums, and wherein the image processing apparatus further comprises a synchronization circuit which synchronizes, with an image processing clock for image processing, a print request signal from a printer controller which controls printing operation, and the print request signal synchronized by said synchronization circuit is commonly used to adjust read timings of the storage sections of the plurality of image processing sections.
