<p>A rotating force transmitting part for a photosensitive drum for a main assembly of an image forming apparatus, wherein the main assembly includes a driving shaft having a rotating force applying portion including a coupling member capable of taking a rotational force transmitting angular position for transmitting the rotational force to the drum and a disengaging angular position in which the coupling member is inclined away from the axis of the drum from the rotational force transmitting angular position, wherein when the drum is dismounted from the main assembly in a direction perpendicular to the axis of the drum, the coupling member moves from the rotational force transmitting angVlar position to the disengaging angular position.</p> |
