A method and program for adjusting the image formation start position in the main scanning direction of the information processing device, the image forming device, and the image forming device.

摘要

PROBLEM TO BE SOLVED: To provide an information processor capable of reducing deviation of a scan start position in the case of performing image formation by an electrophotographic system in which a scan speed of a laser beam is not constant on a photoreceptor surface, and to provide an image forming apparatus, and a method and a program for adjusting an image formation start position in a main scanning direction of the image forming apparatus.SOLUTION: An image processor includes scan speed profile generation means for generating a scan speed profile being information on the scan speed of each main scanning direction in an image forming apparatus in which the scan speed of a laser beam is not constant on a photoreceptor surface, and scan position adjustment amount derivation means for deriving a scan position adjustment amount for regulating distance from a position to be reference of main scan to a write start position of the laser beam onto the photoreceptor surface on the basis of the generated scan speed profile.SELECTED DRAWING: Figure 13
