Abstract: The present invention relates to an image forming apparatus comprising: an exposing means and a developing means. The developing means comprises a plurality of developing devices, a rotating member rotatable while supporting the plurality of the developing devices, and a driving means for the rotation drive of the rotating member for selectively moving the plurality of the developing devices to the developing position such that the driving means transmits driving force to the rotating member via a gear at a drive transmitting position. An angle ?e(°) formed by a straight line linking the rotation center of the rotating member and the drive transmitting position and the tangent of the image bearing member at an exposing position in the image bearing member moving direction satisfies the following relationship with the premise that an pressure angle of the gear is ?(°) and the image bearing member rotating direction is positive: ????e??.

Abstract: In an image reading apparatus having a first original reading device for reading one side of an original guided and fed by a guide, and a second original reading device disposed downstream of the first original reading device for reading the other side of the original, the guide is bent between the first original reading device and the second original reading device so as to shield the respective reading devices. The bending of the guide is done by bending an original feeding path so that direct rays and diffraction rays from each of two light sources may not enter respective photoelectric transfer elements associated with other light source, to thereby shield the photoelectric transfer elements from light of a light source not associated therewith.
