Abstract: An image forming apparatus includes: a rotating body; a sprocket provided coaxially with the rotating body, the sprocket being configured to rotate integrally with the rotating body; a chain including a holder configured to hold a leading end portion of a recording medium, the chain being wound on the sprocket, the chain being configured to rotate so as to transport the recording medium; an annular shaped transfer belt supported by an opposing member opposing the rotating body at an opposing position, the transfer belt being configured to sandwich the recording medium transported by the chain between the transfer belt and the rotating body at the opposing position, in which an image on an outer peripheral surface of the transfer belt is transferred to the recording medium in response to a transfer bias being applied between the rotating body and the opposing member; and a forming member that supports the transfer belt on an upstream side of the opposing position in a transport direction, the forming member being configured to form a contact region in which the transfer belt is brought into contact with the rotating body on the upstream side of the opposing position in the transport direction.

Abstract: An image forming apparatus includes a holding body that holds a formed image; a transport unit that transports a recording medium in a state where a tip of the recording medium is grasped by a grasping portion; a transfer cylinder that has a substantially circular cross section, and that includes a concave portion that accommodates the grasping portion in a direction substantially orthogonal to a rotation direction and transfers an image on the holding body to the recording medium transported by the transport unit by interposing the recording medium transported by the transport unit between the transfer cylinder and the holding body; and an imparting portion that imparts a transport load to the recording medium that is transported to a transfer position at which the image on the holding body is transferred to the recording medium.
