ABSTRACT:
An electrophotographic apparatus achieves miniaturization thereof and improvement of image quality. The shape of an optical scanning device mount frame mounting an optical scanning device is trapezoidal, and asymmetrical with respect to a center line thereof, and a short side part and a long side part are attached to a first and second frames of the apparatus, respectively. A space for attaching parts is available on the side of the first frame, and a driving device is placed inside the first frame so that the apparatus can be miniaturized. Since the optical scanning device mount frame is asymmetrical with respect to the center line thereof, as compared with one having a symmetrical shape, an eigenvalue of vibration can be shifted to a high frequency, and the mount frame is resistant to vibrate. Thus, the fluctuation of a light beam is suppressed, and the image quality can be improved.
