ABSTRACT:
In an image forming apparatus containing a plurality of rollers disposed with generally parallel axes, a retraction plate containing a plurality of rotational couplings is movable between engaged and retracted positions. Each rotational coupling is operative to transmit a rotary force to each cartridge when the retraction plate is in the engaged position. The couplings move laterally in an axial direction of the rollers as the retraction plate moves between the engaged and retracted positions, in response to an applied force. In one embodiment, the retraction plate is rotated about a pivot point to move the couplings between engaged and retracted positions. In another embodiment, the retraction plate is translated laterally in the axial direction of the couplings.
