    摘要: Disclosed is an imaging optical system and an image forming apparatus that provide a small-size design and high resolution. An optical system (telecentric optical system) between the composite focus 4d of an imaging surface side and a laser array 1 is divided into a second lens group 4b and a third lens group 4c and the distance D2 between the third lens group 4c and the laser array 1 is shortened, whereby the spread of incident light into the third lens group 4c is reduced and the aperture of the third lens 4c is reduced. Also, the principal light beam 2a of beam 2 from the laser array 1 is bent at two stages, the second lens group 4b and the third lens group 4c, and the distance D1 between the second lens group 4b and the third lens group 4c is increased, whereby the bend of the principal light beam 2a of the laser beam 2 in the second lens group 4b and the third lens group 4c is reduced, with the result that small aberration is obtained.
