Development cartridge having a switch member to rotate developing unit to a development position
A development cartridge for an image forming apparatus includes a photoconductive unit including a photoconductive drum, a developing unit including a developing roller having a rotation shaft and coupled to the photoconductive unit to be rotatable to a release position where the developing roller is separated from the photoconductive drum, and to a development position where the developing roller contacts the photoconductive drum, and a coupler located between and couplable to the rotation shaft of the developing roller and a rotational power transmission member. When the coupler is coupled to the rotational power transmission member, the coupler is selectively rotatable in a first rotation direction or a second rotation direction by a rotational force from the rotational power transmission member. When the coupler is rotated in the first rotation direction and then in the second rotation direction, transmission of the rotational force to the developing roller is partially interrupted.
