<p><P>PROBLEM TO BE SOLVED: To solve the problem that a contrast of an electrostatic latent image formed to a photoreceptor decreases because a light irradiated from a light emitting element becomes a ghost light passing through a supporting member and illuminates the photoreceptor. <P>SOLUTION: The line head includes a lens array 80 formed with lenses, the supporting member 82 with a translucency, and a light emitting element substrate in which the light emitting element that emits the light is set. The lens array 80 and the supporting member 82 are joined to each other by a mixed agent for bonding in which a gap material 91 lower in optical transmittance than the supporting member 82 is mixed with an ultraviolet curable adhesive 90. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
