Abstract: During one cycle of reciprocating operation of a MEMS mirror, a light receiving sensor detects a falling time at which a laser beam reflected by an upstream-of-sensor mirror and scanned in one direction passes an edge of a regulation portion, and a rising time at which the laser beam scanned in the other opposed direction passes the edge of the regulation portion. A controller executes an arithmetic operation on the basis of the two times detected by the light receiving sensor and controls the operation of the MEMS mirror, which is performed by the driver, such that the detected two times are held at respective setting times.

Abstract: To provide an optical scanning apparatus which is strong against an external stress while suppressing an increase in the number of parts, an inserting portion 6 into which a laser light source unit 1 can be inserted is provided for a frame member 5. In a state where the laser light source unit 1 has been inserted into the inserting portion 6, the laser light source unit 1 and the inserting portion 6 of the frame member 5 are interference-fitted in two positions (front edge side fitting portion 4a and front edge side contact portion 6a; root side fitting portion 4b and root side contact portion 6b) which are away from each other in an optical axial direction.

Abstract: A multi-beam scanning optical system includes a plurality of light sources, a deflecting unit which deflects a plurality of laser beams emitted from the light sources, and a scanning optical unit which focuses the laser beams deflected by the deflecting unit onto the surface of a photosensitive member. The scanning optical unit is set such that lateral chromatic aberration is overcorrected. In addition, among angles formed between each laser beam incident on the surface of the photosensitive member and the normal at the surface of the photosensitive member in a sub-scanning direction, the oscillation wavelength of the light source that emits a laser beam forming the minimum angle is set to a value smaller than the oscillation wavelength of the light source that emits a laser beam forming the maximum angle.
