Zusammenfassung:	To reduce the vibration of an exposure unit in comparison to a case where one dynamic vibration absorber is provided in the exposure unit.SOLUTION: An exposure device comprises: an exposure unit which has a plurality of light-emitting elements arranged along the axial direction of a rotating image holding body, is positioned with respect to the image holding body on both ends in the axial direction and emits the light to the image holding body to expose the image holding body; and a plurality of dynamic vibration absorbers which are attached to the exposure unit, have the mutually-different characteristic frequencies at a predetermined reference temperature and absorb the vibration of the exposure unit.SELECTED DRAWING: Figure 4 【課題】露光部に一つの動吸振器を設ける場合と比較して、露光部の振動を低減する。【解決手段】回転する像保持体の軸方向に沿って並ぶ複数の発光素子を備え、軸方向の両端で像保持体に対し位置決めされ、像保持体に光を出射して像保持体を露光する露光部と、露光部に取り付けられ、予め定めた基準温度での固有振動数が互いに異なり、露光部の振動を吸収する複数の動吸振器とを備える露光装置。【選択図】図４
