Abstract:
An exposure head includes a light emitting element and a imaging optical system having a first region and a second region and contrived such that a slope of a long dimension of a spot diagram formed by light emitted from the light emitting element that passes through the first region is different from a slope of a long dimension of a spot diagram formed by light emitted from the light emitting element that passes through the second region.
