    摘要： An image forming apparatus provided with a photoreceptor with an internal gear includes the internal gear in a photoreceptor drum, a pinion gear in engagement with the internal gear, and a cleaning unit and a developer unit which apply contact pressure onto the photoreceptor drum. The pinion gear is provided in such an area that a resulting force of the contact pressure respectively applied from the process elements does not cause a distortion of the photoreceptor drum which exceeds an axial backlash determined in initialization according to a distance between axes of the pinion gear and the internal gear. The described arrangement prevents interference between non-driving surfaces of the internal gear and the pinion gear. As a result, a smooth rotary motion of the photoreceptor drum can be ensured, thereby preventing an image defect caused by an unstable rotary motion of the photoreceptor drum.

    摘要： An automatic original document feeder is provided which feeds an original document placed on an original document table so as to invert the original document thus fed through an inverting transport section for its transport to an image exposing position with an image surface of the original document being inverted. A transport belt is provided for feeding the original document into the inverting transport section, and an original document stopper is provided for stopping the original document transported by the transport belt once at a position before it is fed into the inverting transport section in order to again transport, by the transport belt, the original document stopped by the original document stopper so as to be fed into the inverting transport section for transporting the inverted original document to the image exposing position.
