レーザ光学系。 The laser beam from the semiconductor laser is focused by the first imaging optical system, hits the deflection reflection surface of the optical deflector, is reflected by the deflection reflection surface, is focused by the second imaging optical system, and is focused onto the photoreceptor. In a laser optical system of an electrophotographic apparatus that performs optical scanning, an engaging portion with which one end of a lever-like jig engages is provided on a lens holder that holds the first imaging optical system, and the lens holder is always held by a spring. A positioning and holding mechanism for positioning by pressing with a biasing force is provided, and when one end of the lever-like jig is engaged with the engaging portion and the jig is swung about its fulcrum, it resists the positioning and holding mechanism. A laser optical system for an electrophotographic apparatus, comprising a guide section that guides the lens holder so that it can be moved and adjusted back and forth along an optical axis.
