Optical scanning apparatus

An optical scanning apparatus comprising:

• a light source that emits a laser light;
• a lens through which the laser light emitted from the light source is passed;
• a support member directly supporting the lens;
• and
• a deflect device that deflects the laser light and scans an image bearing member with the laser light,
• wherein the support member includes a plate-shaped protrusion extending to a downstream of a laser light emitting surface of the lens with regard to a laser light emitting direction,
• wherein as viewed in the laser light emitting direction, the plate-shaped protrusion surrounds a whole of the lens, and
• wherein as viewed in the laser light emitting direction, an area surrounded by the plate-shaped protrusion is a quadrilateral.

An optical scanning apparatus comprising:

• a light source that emits a laser light;
• a lens through which the laser light emitted from the light source is passed;
• a support member supporting the lens;
• and
• a deflect device that deflects the laser light and scans an image bearing member with the laser light,
• wherein the support member includes a protruding portion projecting to the downstream side in a laser light emitting direction with respect to a laser light emitting surface of the lens,
• wherein the support member including a bonding surface on which the lens is adhered, and
• wherein the bonding surface is provided at a position opposite to face a laser light incident surface of the lens with each other.
