OPTICAL WRITING DEVICE, IMAGE FORMING APPARATUS, AND MANUFACTURING METHOD OF OPTICAL WRITING DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent deterioration in image quality due to a change of a dither pattern while suppressing an increase in cost with a simple configuration in skew correction in an optical writing device.SOLUTION: When the locus of the reaching point of a light beam from a reflection mirror 280 on a photoreceptor drum 109 is inclined relative to a direction perpendicular to the direction of rotation of the photoreceptor drum 109 due to the incompatibility between the scanning speed of the light beam and the rotation speed of the photoreceptor drum 109, an optical writing device inputs pixel information stored in a line memory for each main scanning line into a light emission control unit while adjusting the timing, so as to shift pixel information to be input to one of two light source devices 281BK and 281C in the sub scanning direction at the middle of the main scanning line.
