<p>PURPOSE:To provide an LED printing head requiring no adjustment at the time of the attachment of the LED printing head to a photosensitive drum, capable of easily performing focus matching and capable of enhancing assembling efficiency or reducing production cost. CONSTITUTION:The distance between the opposed surfaces of an LED 14 and the lens array 20 of an image forming system is determined on the basis of the surface opposed to the LED of the lens array of the image forming system by a head cover 18 and the distance between the opposed surfaces of the lens array 20 of the image forming system and a photosensitive drum 64 is determined on the basis of the surface opposed to the photosensitive drum of the lens array 20 of the image forming system by a striking member 22 having a striking part.</p> |
