    Abstract: PROBLEM TO BE SOLVED: To provide an optical scanner in which the length of a unit in the advance direction of light is made compact while keeping an optical path length from a focusing lens to an object to be irradiated with light, and to provide an image forming apparatus. SOLUTION: A fixing member mounting face 702 being a fixing member mounting part is provided at the downstream side of a cylindrical lens 403 being a focusing lens in the advance direction of light, thus the cylindrical lens 403 can be more closely arranged to an aperture 106 side than an example in which the fixing member mounting face 702 is provided at the upstream side of the cylindrical lens 403 in the advance direction of light. Thus, the optical path length from a photoreceptor to a polygon scanner is made short while keeping the shape of the beam spot diameter of write-in light and light quantity on the photoreceptor. As a result, the unit is made compact while keeping the beam spot diameter and the light quantity. COPYRIGHT: (C)2010,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide an optical unit capable of regulating a magnification by providing a cut-out part to allow a wide range regulation. SOLUTION: The cut-out parts 39, 44 having respectively small cut-out parts 39a, 44a are formed respectively in a lens holding member 33 and a lens unit holding member 34, a head part 45 of a jig is inserted into the small cut-out parts 39a, 44a, to be rotated along an arrow mark direction, and the lens holding member 33 and the lens unit holding member 34 are thereby moved relatively along an optical axis L direction. The relative moving direction between the lens holding member 33 and the lens unit holding member 34 can be changed by rotating the jig counterclockwise or by rotating the jig clockwise, according to this manner.
