<p>A printhead for forming an image on an image carrier includes: an array of light emitting devices provided with a plurality of light emitting devices arranged in a such a way that the plurality of light emitting devices form at least one column and are independently driven; a shadow mask provided with a plurality of opening units arranged in such a way that the plurality of opening units form at least one column; and an array of micro lenses provided with a plurality of micro lenses arranged in such a way that the plurality of the micro lenses form at least one column. Each of the opening units of the shadow mask is corresponding to each of the light emitting devices of the array of the light emitting devices; each of the micro lenses of the array of the micro lenses is corresponded to each of the opening units of the shadow mask; and, therefore, after a light generated at each of the light emitting devices passes through the opening unit corresponding to the shadow mask, the shadow mask focuses an image on the image carrier by being connected with passing through the micro lens corresponding to the array of the micro lenses.</p> |
