    摘要: 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.

    摘要: A sheet feeding device includes a driving roller, a driven roller rotated by the rotation of the driving roller, a non-conductive feeding guide, a conductive frame, a conductive bearing and an urging member to urge the driven roller toward the driving roller. The feeding guide includes a supporting portion to displaceably support the rotation shaft in an urging direction. The frame includes a positioning portion to position the driven roller in the urging direction by contact with the rotation shaft in a state in which the driving roller is urged by the driven roller.
