    摘要： According to an exposure device includes an exposure section, a lighting drive section, a first temperature detector and a second temperature detector. The exposure section has a plurality of light-emitting elements. The lighting drive section determines light-emitting energies of the respective light-emitting elements and drives to light the respective light-emitting elements in accordance with the determined light-emitting energies. The first temperature detector is provided in the exposure section. The second temperature detector is provided outside the exposure section. The lighting drive section determines the light-emitting energies of the respective light-emitting elements based on a temperature detected by the first temperature detector and a temperature detected by the second temperature detector.

    摘要： An exposure device includes a plurality of light-emitting elements, a lighting driver, a first storage, a reader, a shading correction unit and a second storage. The lighting driver drives and lights up the light-emitting elements based on image data. The first storage stores light amount unevenness correction values of the respective light-emitting elements. The reader reads the light amount unevenness correction values stored in the first storage. The shading correction unit executes shading correction for the light amount unevenness correction values read by the reader. The second storage stores correction values obtained by having the shading correction unit to execute the shading correction for the light amount unevenness correction values. The lighting driver controls light power of the respective light-emitting elements based on the correction values stored in the second storage.
