Abstract
A print head comprises a plurality of light emitting devices which are arranged such that the adjacent light emitting devices are stepped from each other in the rotation direction of a photosensitive member, or a plurality of light emitting devices which are disposed linearly such that the light emitting devices emit light at different timings each other by employing a delay mechanism. Consequently, it is possible to provide the output pattern capable of directing the human eyes in two dimensions so as to reduce the visible difference in the image density.
