Patent ID: 8228572

Claim:
An image processing apparatus for transmitting an image to be printed to an image forming apparatus, comprising: a receiving unit that receives from the image forming apparatus an adjustment value of a print position for each sheet feeding port of a plurality of sheet feeding ports, the adjustment value corresponding to a deviation in a main scanning direction of a sheet feeding position; a discriminating unit that discriminates information of a sheet feeding port of a sheet which is used to print based on a print request, to determine at least one sheet feeding port for printing; a correction amount deciding unit that decides a correction amount in the main scanning direction for a main scan positional deviation of the at least one sheet feeding port determined by the discriminating unit based on a result of the discrimination of the discriminating unit and a corresponding adjustment value received by the receiving unit; and a sub-scan positional deviation correcting unit that corrects a positional deviation in a sub-scanning direction of the image to be printed by using both (i) the correction amount decided by the correction amount deciding unit and (ii) information showing the positional deviation in the sub-scanning direction of the image forming apparatus.
