Line Head And An Image Forming Apparatus Using The Line Head

An image forming apparatus, comprising:

• a latent image carrier;
• and
• a line head that includes a substrate which is transmissive and has a first surface and a second surface facing the first surface, a plurality of light emitting elements which are arranged on the first surface of the substrate and emit light beams, a wiring which is arranged on the first surface of the substrate and is connected with the plurality of light emitting elements, a lens array that has a plurality of imaging lenses which are arranged facing the light emitting elements at a side of the second surface of the substrate and focus the light beams emitted from the facing light emitting elements to form spots on a surface of the latent image carrier, and an optical sensor which detects the light beams emitted from the light emitting elements and is arranged on the second surface of the substrate.
