Abstract
An optical writing apparatus whereby non-light-emitting portions that might exist between adjacent light-emitting elements arranged in parallel rows can be substantially eliminated either in the direction of the rows or in the direction perpendicular to the row direction. In addition, dotted latent electrostatic images can be formed in such a way that adjacent dots partially overlap with each other, thus contributing to improved image quality and resolution. Further, because light-emitting elements are connected to a common anode electrode, a reduced number of electronic devices is required to drive the elements.
