Patent ID: 8388092

Claim:
An image forming apparatus for generating print data for performing image formation by performing using a print head a plurality of reciprocating print scans upon the same printing region on a print medium, the image forming apparatus comprising: a division unit configured to divide, in units of pixels, image information into a plurality of scans, while controlling division coefficients, the division coefficients being based on a number of times of scans determined for each printing region; and a quantization unit configured to quantize each of the image information divided by the division unit, wherein the number of times of scans differs among at least two printing regions on one recording medium, and wherein the division unit sets, in a printing region of which the number of times of scans differs from the number of times of scans of an adjacent printing region, the division coefficients based on a paper feeding amount and a changing point of the number of times of scans.
