Abstract:
In a case of performing a second rotation control to match the rotation phase of a first rotational polygon mirror with the rotation phase of a second rotational polygon mirror in a rising period, a period during which a non-image region is irradiated with light from both or one of a first light source and a second light source is controlled to be a second period longer than a first period.
