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.

Abstract: A transfer device includes: a transfer drum that has a groove-like recess extending in an axial direction in an outer circumferential portion thereof, rotates about an axis thereof, and comes into contact with a medium being transported at a portion thereof on an upstream side of the recess in a rotation direction; a nip member, the nip member and the transfer drum forming therebetween a nip part where the medium is nipped; an application member that applies a voltage to the nip part where the medium is nipped, so that an image is transferred to the medium; and a contact mechanism that causes the nip member to come into contact only with a portion on the upstream side of the recess in the transfer drum in the rotation direction at a transfer-start time when the transfer of the image to the medium starts.
