A development cartridge detachable from a main body of an image forming apparatus, the development cartridge comprising: a photoconductive unit including a photoconductive drum and an interfering portion; 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 to form a development nip; an elastic member configured to provide an elastic force to maintain the developing unit at the development position; characterized in that: the development cartridge further includes: a coupler couplable to a driving motor provided in the main body when the development cartridge is detachably mounted on the main body, and when the coupler is coupled to the driving motor, the coupler is selectively rotatable in at least one of two coupler directions; and a switching member mounted on the rotation shaft of the developing roller to be rotatable about the rotation shaft of the developing roller by being coupled to the coupler so that when the coupler is rotated in the at least one coupler direction, the switching member is switched to a first state where the switching member contacts the interfering portion of the photoconductive unit to rotate the developing unit to the release position, and when the coupler is rotated in the other coupler direction, the switching member is switched to a second state where the switching member is separated from the interfering portion of the photoconductive unit to allow the developing unit to rotate to the development position due to the elastic force of the elastic member. a photoconductive unit including a photoconductive drum and an interfering portion; 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 to form a development nip; an elastic member configured to provide an elastic force to maintain the developing unit at the development position; characterized in that: the development cartridge further includes: a coupler couplable to a driving motor provided in the main body when the development cartridge is detachably mounted on the main body, and when the coupler is coupled to the driving motor, the coupler is selectively rotatable in at least one of two coupler directions; and a switching member mounted on the rotation shaft of the developing roller to be rotatable about the rotation shaft of the developing roller by being coupled to the coupler so that when the coupler is rotated in the at least one coupler direction, the switching member is switched to a first state where the switching member contacts the interfering portion of the photoconductive unit to rotate the developing unit to the release position, and when the coupler is rotated in the other coupler direction, the switching member is switched to a second state where the switching member is separated from the interfering portion of the photoconductive unit to allow the developing unit to rotate to the development position due to the elastic force of the elastic member. a coupler couplable to a driving motor provided in the main body when the development cartridge is detachably mounted on the main body, and when the coupler is coupled to the driving motor, the coupler is selectively rotatable in at least one of two coupler directions; and a switching member mounted on the rotation shaft of the developing roller to be rotatable about the rotation shaft of the developing roller by being coupled to the coupler so that when the coupler is rotated in the at least one coupler direction, the switching member is switched to a first state where the switching member contacts the interfering portion of the photoconductive unit to rotate the developing unit to the release position, and when the coupler is rotated in the other coupler direction, the switching member is switched to a second state where the switching member is separated from the interfering portion of the photoconductive unit to allow the developing unit to rotate to the development position due to the elastic force of the elastic member.
