摘要： An optical head is adapted to form an electrostatic latent image on an image carrier. A transparent substrate has a first face adapted to oppose the image carrier and a second face opposing the first face. An organic EL photo emitter is disposed so as to oppose the second face of the substrate. In the photo emitter, a light emitting layer is adapted to emit light irradiating the image carrier to form the electrostatic latent image. An electrode layer is laminated on the light emitting layer. A reflection reducer eliminates stray light generated when the light emitted from the light emitting layer is reflected by at least the electrode layer.

摘要： A line head includes light-emitting element lines formed by arranging a plurality of light sources in a line shape in a main scanning direction. Each of the light sources is turned on/off corresponding to image data. Light beams emitted from the light sources pass through a lens array to form imaged spots on an exposed surface. The imaged spots generated by making the light beams emitted from the plurality of light sources imaged on the exposed surface are shifted by inches in the main scanning direction or a sub-scanning direction so as to overlap each other, thereby forming images. A gray-scale image of the images has a screen structure displayed on the basis of an area of dots or lines having a predetermined pitch. A diameter of each of the imaged spots formed on the exposed surface is set to be larger than a pitch between pixels and smaller than a pitch between lines or dots forming the screen. Gradation of an image is displayed by a combination of binary states of ON/OFF of each of the light sources.
