Abstract
An optical writing device includes light-emitting element array substrates, connecting members, self-focusing rod-shaped lens arrays, and a package case. Each of the light-emitting element array substrates includes light-emitting elements arranged in a line for emitting light in a straight line. The light-emitting element array substrates are placed in parallel and partly in an overlapping formation to be able to write on an area of a predetermined width in a direction in which the plurality of light-emitting elements of each of the light-emitting element array substrates are arranged in the line. Each connecting members connects two adjacent light-emitting element array substrates to each other around a position, at which an operation for writing dots with the light-emitting elements, is switched from one of the light-emitting element array substrates to a subsequent one of the light-emitting element array substrates. The self-focusing rod-shaped lens arrays are arranged in positions corresponding to positions of the light-emitting elements of the light-emitting element array substrates. The package case packages the light-emitting element array substrates and the self-focusing rod-shaped lens arrays into one device.
