    • An exposure head includes a linear light emitting element array, in which light emitting elements are aligned, and a lens array, in which lenses are aligned. The light emitting elements are caused to emit light uniformly, based on a common command signal. The amount of light emitted through the lens array is measured at a measuring pitch less than or equal to the arrangement pitch of the light emitting elements, across the length of the array. Correction coefficients for correcting the amount of light emitted from each light emitting element to shorten the period of fluctuation in the amount of light, which is a period of the lens arrangement pitch within the lens array, are calculated, based on the measured amount of light. During exposure, the amounts of light emitted from the light emitting elements, which are controlled based on image signals, are corrected based on the correction coefficients.
