PROBLEM TO BE SOLVED: To provide an optical writing device which inhibits vibration of an optical writing device body compared to a case where a distance between two fixing parts for fixing the optical writing device body is not changed, and to provide an image formation device.SOLUTION: An optical writing device included in an image formation device has: a printer head 202; and a machine screw member 412 and a machine screw member 312 which fix the printer head 202. The printer head 202 has: an LED circuit board; a rod lens array 210; and a housing 204 to which the LED circuit board and the rod lens array 210 are attached. The machine screw member 312 is attached to an elongated hole 204b formed in the housing 204 so as to be arranged along a longitudinal direction of the housing 204 and may move along the elongated hole 204b.SELECTED DRAWING: Figure 4 【課題】光書込み装置本体を固定する２つの固定部の間の距離を変更しない場合に比べて、光書込み装置本体の振動を抑制することができる光書込み装置及び画像形成装置を提供する。【解決手段】画像形成装置が有する光書込み装置は、プリンタヘッド２０２と、プリンタヘッド２０２を固定するビス部材４１２及びビス部材３１２とを有し、プリンタヘッド２０２は、ＬＥＤ回路基板と、ロッドレンズアレイ２１０と、ＬＥＤ回路基板及びロッドレンズアレイ２１０が装着されているハウジング２０４とを有し、ビス部材３１２は、ハウジング２０４の長手方向に沿ってハウジング２０４に形成された長孔２０４ｂに装着されていて、長孔２０４ｂに沿って移動可能である。【選択図】図４
