Patent ID: 7961208

Claim:
An image forming apparatus for forming an image corresponding to rasterized original image data by dividing the rasterized original image data into regions in accordance with N (N being an integer greater than or equal to 2) recording heads, and scanning a single recording body by simultaneously irradiating recording beams from the N recording heads, the image forming apparatus comprising: a positional displacement information storing unit configured to hold positional displacement information including positional displacements of the recording beams of the recording heads; a rasterized original image data storing unit configured to hold the rasterized original image data; a corrected image data generating unit configured to generate corrected image data divided into the regions in accordance with the recording heads, the corrected image data being obtained by changing the rasterized original image data held in the rasterized original image data storing unit based on the positional displacement information so that the positional displacements are corrected in a main scanning direction and a sub scanning direction when the recording beams are irradiated; and a scanning information generating unit configured to generate scanning information based on the positional displacement information, the scanning information including positions and orders for the recording beams to scan the recording body to record the corrected image data.
