<P>PROBLEM TO BE SOLVED: To provide an optical print head that can successfully correct image deterioration with age due to temperature fluctuation, and make full use of the properties of a LEDA system, such as quietness or miniaturization. <P>SOLUTION: The optical print head includes: first substrates on which a plurality of light sources are arrayed; a second substrate on which the first substrates are arranged and arrayed in a plurality of lines; a lens array arranged with a predetermined interval relative to the second substrate; and a housing member arranged to surround the second substrate. In the optical print head in which light emitted from the light sources is concentrated to a surface to be exposed by using the lens array, the drive current for the adjacent light sources between the first substrates is adjusted according to a gap between the adjacent first substrates that is varied with temperature fluctuation to bring the state of exposure distribution back to an ideal state. <P>COPYRIGHT: (C)2013,JPO&INPIT |
