    Abstract: A transport device includes: a rotating member that rotates; a circulating member that is loop-shaped and wrapped around the rotating member, the circulating member being circulated by rotation of the rotating member; and a pair of pinching members attached to an attachment portion of the circulating member and circulated together with the circulating member, the pair of pinching members changing from a separated state, in which the pair of pinching members are separated from each other, to a closely positioned state to pinch a transport object that has entered a space between the pair of pinching members in the separated state. The attachment portion of the circulating member is in contact with the rotating member when the transport object starts to enter the space between the pair of pinching members in the separated state.

    Abstract: Provided is an image forming apparatus including: an annular transfer belt having an outer surface on which an image is transferred; a transferring unit including a transfer cylinder having a transfer area that sandwiches a recording medium with the outer surface of the transfer belt to transfer the image from the outer surface of the transfer belt to the recording medium, and a pair of first rotating bodies disposed on both axial end sides of the transfer cylinder; a pair of circulating members each being wound around the first rotating body and being circulated by rotation of the first rotating bodies; and a holding unit attached to the circulating members, the holding unit configured to hold the recording medium, transport the recording medium with circulation of the circulating members, and pass the recording medium through the transfer area.

    Abstract: An image forming apparatus includes: a rotating body having a recess in an outer peripheral surface thereof; a sprocket provided coaxially with the rotating body to rotate integrally with the rotating body; a chain having plural links, the chain being wound around the sprocket to circulate in a circulating direction so as to shift from a rotary movement in which the chain rotates in an arc shape conforming to an outer periphery of the sprocket along with the sprocket, to a linear movement; a holder fixed to at least one link of the links of the chain, the holder being configured to hold a leading end portion of a recording medium, the holder being configured to transport the recording medium by performing the rotary movement along with the rotating body and the chain in a state of (i) holding the leading end portion of the recording medium placed on the outer peripheral surface of the rotating body and (ii) being located in the recess, and then shifting to the linear movement along with the chain; and an image forming unit configured to form an image on the recording medium placed on the outer peripheral surface of the rotating body, in which a holding position where the holder holds the recording medium is arranged downstream of an upstream roller of rollers of a most downstream link in the circulating direction among the at least one link to which the holder is fixed.
