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.
