OPTICAL WRITING CONTROL DEVICE, IMAGE FORMING APPARATUS AND METHOD FOR CONTROLLING OPTICAL WRITING DEVICE

摘要

PROBLEM TO BE SOLVED: To achieve balance of reduction of toner consumption for drawing correction patterns and accuracy of device operation.SOLUTION: Two types of correction patterns can be drawn as the correction pattern to correct a transfer position: a narrow width pattern having a width in a main scanning direction corresponding to a width in the main scanning direction of a detection range of a pattern detecting sensor 117 and a wide width pattern having a width wider than the width of the narrow width pattern. A LEDA is controlled to emit light to draw the narrow width pattern after calculation of a correction value based on a detection signal of the wide width pattern is completed properly.
