装置。[Claims for Utility Model Registration] (1) A light emitting element array consisting of a plurality of light emitting elements arranged at regular intervals in the vicinity of a photoconductive latent image carrier, and a light image from each light emitting element being a focusing optical fiber bundle that forms an image on the image carrier, selectively causes the light emitting element to emit light based on the image signal to form an electrostatic latent image on the latent image carrier, and also forms the electrostatic latent image on the latent image carrier after printing is completed. In a printer device in which the electrostatic charges on the latent image carrier are erased by uniformly emitting light from the light emitting elements, a light image from each light emitting element is formed between the latent image carrier and the light emitting element array. A printer device characterized in that a focal point moving member for moving image positions and superimposing the light images on each other is removably provided, so that the intensity of irradiation onto the latent image carrier is made uniform. (2) The printer device according to claim 1, wherein the focus moving member is comprised of a pair of optically transparent parallel flat plates.
