<p>PROBLEM TO BE SOLVED: To provide an LED array image bar wherein uneveness of spaces among LED array chips is corrected for producing faultless images in high resolution at high speed. SOLUTION: For the image-forming apparatus, an arraylike light source formed on a substrate 2-1 by connecting at least two device chips 2-3 with luminescent points arranged in a plurality of lines thereon is used. On connecting the device chips, a line being a basis for the substrate 2-1 is made to be a principal axis 2-2, and a point on which the luminescent point of the device chip 2-3 is positively projected on the principal axis 2-2 is made to be a positive projection point 2-6, and when a segment connecting the positive projection points 2-6 for each of the device chips 2-3 is made to be a principal axis segment, the device chips 2-3 adjoining one another are stuck to the surface of the substrate 2-1 so that the principal axis segments are arranged with overlapping areas provided, and the space between the adjoining positive projection points 2-6 is made to be different from one another in the overlapping area for each of the adjoining device chips 2-3, and the structure is so constructed that driving for the luminescent points is shifted among the device chips 2-3 with any one point in the overlapping area made to be a boundary.</p> |
