Abstract:
An image forming apparatus includes image forming stations including respective electrophotographic photosensitive drums; an image transfer belt contactable to the drums; image transfer rollers, contactable to the transfer belt to urge the belt to the drums for transferring the toner images from the drums onto the belt, the rollers being provided with respective rotational shafts about an axis of which the rollers are rotatable; and a slidable member slidable in a direction in which the stations are arranged to retract the rollers away from the corresponding drums, the slidable member being provided with inclined surfaces contactable to the shafts, the inclined surfaces being disposed at such positions that the rollers are retracted from respective drums sequentially with the movement of the slidable member in the direction.

Claim (Index 1):
An image forming apparatus comprising:\n an apparatus main assembly; a unit detachably mountable to said apparatus main assembly; a first coupling, provided on said apparatus main assembly, for being rotated by power from a driving source; and a second coupling, provided on said unit, for being rotated by engaging with said first coupling, wherein one of said first coupling and said second coupling has a recessed shape and the other of said first coupling and said second coupling has a projected shape, wherein at least one of an outer peripheral surface of the projected-shape coupling and an inner peripheral surface of the recessed-shape coupling has an inclined surface, wherein at least one of said first coupling and said second coupling is retractable toward a direction parallel to a rotation shaft thereof, and wherein said image forming apparatus has a structure such that a rotation axis of said second coupling is movable relative to a rotation axis of said first coupling in a disengaging direction of said unit by a force exerted in the disengaging direction of said unit when said unit is pulled out from said apparatus main assembly in the disengaging direction perpendicular to the rotation axis of said first coupling and then by contact of the inclined surface and by such relative movement of the rotation axes, at least one of said first coupling and said second coupling starts retracting along the inclined surface in the direction parallel to the rotation axis from a state in which said first and second couplings are engaged to be rotated.
