An electrophotographic device having an optical system constituted by a lens for shaping a laser beam, which is integrally molded with an optical base and has grooves formed on one of the bottom and side surfaces with high precision from a reference position. A processed lens stand, a cylindrical lens holder whose outer periphery and a lens storage part are processed with high precision, and the top end of the lens holder is pressed from the low precision processed side of the lens stand by 15 degrees to A lens fixing device comprising a leaf spring bent at an angle of 75 degrees, and a screw for pressing and fixing the lens holder to the high-precision machined surface of the groove via the leaf spring. 2. The lens fixing device according to claim 1, which is a registered utility model, characterized in that the outer periphery of the lens holder is also machined with grooves so that the generatrix direction of the cylindrical lens and the position of the lens can be recognized on the outer periphery of the lens holder. 3. A utility model characterized in that the mounting position of the lens in the optical axis direction is recognized by cutting out a part of the groove of the lens stand and aligning the processed surface with the lens holder narrow groove of claim 2. A lens fixing device according to claim 1.
