摘要：
A line head, includes a plurality of light emitting elements, which are arranged in a line and a controller, which applies constant voltage to the light emitting elements on the basis of gradation data. Correction data for correcting a dispersion of light quantities of the respective light emitting elements are added to the gradation data. Also, the correction data of electric quantity for correcting a dispersion of light quantities of the respective light emitting elements are formed by the gradation data.
