Abstract

See full text

At image formation time, when the light amount setting value used in the image formation is equal to or larger than the light amount value Xm affected by the stray light, a corrected signal width Tw corresponding to the light amount setting value used in the image formation is calculated from the increase ratio αn of the signal width tn of a detection signal acquired in a region having a light amount value smaller than the light amount value Xm affected by the stray light; and a synchronization signal is generated on the basis of a center position of the corrected signal width Tw.
