An optical writing head is provided in which the deviation of a line of light spots on the photosensitive drum in a sub-scanning direction due to manufacturing dispersion of a rod-lens array is corrected. In the optical writing head comprising a self-scanning light-emitting element array and a rod-lens array for projecting light emitted from the self-scanning light-emitting element array onto the photosensitive drum, the timing of a start pulse supplied to the start pulse line every chip is regulated to correct the deviation of the line of light spots.
