摘要： An exposure device includes plural light emitting elements that light in turn for exposure, plural driving elements that drive each of the light emitting elements and a time changing member that changes one time period of a switching signal to switch light emitting elements driven by the driving elements among the plurality of light emitting elements in turn from a reference time, depending on an image forming speed, wherein the time changing member changes the one time period from the reference time for some of the light emitting elements during one main scan, and maintains the one time period as the reference time for the remaining light emitting elements.

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.
