Abstract
The optical scanning apparatus including a light source unit having plurality laser light sources for emitting laser light and one lens in which the laser light emitted from the plurality laser light sources is transmitted, a deflect device that deflects and scans the laser light on an image bearing member, an optical member that images the laser light on the image bearing member, a housing that internally includes the deflect device and the optical member, the housing forms an opening portion that passes through the laser light emitted from the plurality of the laser light sources, and an elastic member that blocks a gap between the lens and the opening portion, the elastic member being pinched between the lens and the housing. It achieves sealing of the flow-in path and sealing of the gap between the light source unit and the housing with a simple configuration.
