Abstract
Official abstract text for this publication.
An image forming apparatus includes: an annular transfer belt having an outer surface on which an image is transferred; a nip portion that forms a nip region for nipping a recording medium with an outer surface of the transfer belt; a facing portion that faces the nip region from an inner side of the transfer belt and transfers the image from the transfer belt to the recording medium in the nip region by charging the transfer belt; and a transport unit including a holding portion that holds the recording medium, transports the recording medium by moving the holding portion, and causes the recording medium together with the holding portion to pass the nip region while holding the recording medium at the holding portion.
First claim
Opening claim text (preview).
What is claimed is: 1. An image forming apparatus comprising: an annular transfer belt having an outer surface on which a toner image is transferred; a transfer portion that has a nip region for nipping a recording medium with an outer surface of the transfer belt, and transfers the toner image from the transfer belt to the recording medium; a facing portion that faces the nip region from an inner side of the transfer belt and transfers the toner image, with the transfer portion, from the transfer belt to the recording medium in the nip region; and a transport unit comprising a holding portion that holds the recording medium, transports the recording medium by moving the holding portion, and causes the recording medium together with the holding portion to pass the nip region while holding the recording medium at the holding portion, wherein the transport unit has a chain that is wound around on the transfer portion and to which the holding portion is attached, and transports the recording medium by circulating the chain, and wherein the chain is wound around on the nip region. 2. The image forming apparatus according to claim 1 , wherein the facing portion comprises an upstream side facing portion disposed on an upstream side with respect to a center of the nip region in the transport direction of the transport unit. 3. The image forming apparatus according to claim 1 , wherein the recording medium is peeled from the transfer portion before the recording medium is peeled from the transfer belt on a downstream side in the transport direction of the transport unit with respect to the nip region. 4. The image forming apparatus according to claim 1 , wherein the recording medium is peeled from the nip portion transfer portion after the recording medium is peeled from the transfer belt on a downstream side in the transport direction of the transport unit with respect to the nip region. 5. The image forming apparatus according to claim 1 , configured to switch between: a state in which the recording medium is peeled from the transfer portion before the recording medium is peeled from the transfer belt on the downstream side in the transport direction of the transport unit with respect to the nip region; and a state in which the recording medium is peeled from the nip portion after the recording medium is peeled from the transfer belt on the downstream side in the transport direction of the transport unit with respect to the nip region.
