Abstract
A print head for writing data onto a photoreceptor, including a light source panel of light emitting elements arranged in a matrix, optical systems arranged in a matching matrix, light receiving elements, and a corrector. The optical systems each include at least a light-source-side lens and an image-side lens, and focus light from the light emitting elements onto different regions of the photoreceptor. The light receiving elements each include a light receiving surface disposed in a leaked light region and detect light incident on the light receiving surface. The leaked light region is in a gap between the light-source-side lens and the image-side lens of each of the optical systems occupied by optical paths of light transmitted through the light-source-side lenses but not incident on the image-side lenses. The corrector corrects amounts of light to be emitted from the light emitting elements based on the light detected.
