Abstract: An image forming apparatus includes a drum gear having a first guide slot and a cam, a clamp having a first interlocking pin inserted into the first guide slot and a cam pin is interlocked with the cam. A release lever is mounted on a support plate on which a shaft of a drum is supported. A lifter having one end with a second guide slot formed therein is coupled to the first interlocking pin. The other end of the lifter has a second interlocking pin interlocked with the release lever. The apparatus can shorten the overall printing time by reducing the additional time required for ejecting a sheet of paper because the clamp is operated in cooperation with rotation of the drum during a printing operation.
