    Abstract: Disclosed are a transfer unit and an image forming apparatus. The image forming apparatus includes a main body frame on which one or more image carrying bodies are is supported and a transfer unit coupled to the main body frame. The transfer unit receives one or more images respectively from the one or more image carrying bodies, and may include, for example, an intermediate transfer belt for receiving thereon the one or more images, a transfer roller corresponding to an image carrying body and movable between a first position at which the transfer roller contacts the image carrying body and a second position at which the transfer roller is spaced apart from the image carrying body, an elastic member elastically biasing the transfer roller toward the first position and a guide structure that guides the movement of the transfer roller in a manner opposing the elastic force of the elastic member so as to reduce the speed at which the transfer roller moves from the second position to the first position and to thereby reduce the force of impact with which the transfer roller makes contact with the image carrying body.
