Optical writing apparatus and image forming apparatus

Abstract

To provide an optical writing apparatus in which an adhesive agent can be peeled without being adhered onto a counterpart member even if a housing cover is removed, and sealability can be secured when re-installing the cover.SOLUTION: An optical writing apparatus has: a light source which outputs light; optical scanning means for changing a traveling direction of the light by reflecting and rotating the light; a scanning optical system for making the scan speed of light reflected by the optical scanning means constant; and a housing which houses the light source, the optical scanning means and the scanning optical system, where the housing has: at least a first member; a second member which constitutes the housing by being fixed opposing to the first member; and a sealing member provided between an abutting part of the first member and an abutting part of the second member, and either one of the abutting part of the first member and the abutting part of the second member has a mold-releasing part to which mold-releasing treatment is applied.SELECTED DRAWING: Figure 1
