Transport device and image forming apparatus

A transport device comprising:

• a transport roller configured to transport a transport target material sent from an accommodating unit;
• a nip section configured to
• nip the transport target material with the transport roller, and
• prevent multi-feed of the transport target material;
• and
• transport path surfaces, at least one of the transport path surfaces being disposed upstream of the nip section in a transport direction, at least another one of the transport path surfaces being disposed downstream of the nip section in the transport direction, the transport path surfaces being configured to cause a posture of the transport target material to be a posture such that a contact area between the transport target material and the transport roller is larger than a contact area between the transport target material and the nip section.

A transport device comprising:

• transport means for transporting a transport target material sent from an accommodating unit;
• nip means for
• nipping the transport target material with the transport means, and
• preventing multi-feed of the transport target material;
• a first transport path surface disposed upstream of the nip means in a transport direction to face a transport means side of the nip means, the first transport path surface comprising a bottom portion recessed toward a nip means side of the transport means and disposed beyond a nip line between the transport means and the nip means on a nip means side of the nip line, a top portion located downstream of the bottom portion in the transport direction and protruding toward the transport means side beyond the nip line on a transport means side of the nip line, a downward inclination portion extending in the downstream direction from beyond the nip line on the transport means side to the bottom portion, and an upward inclination portion extending in the downstream direction from the bottom portion to the top portion;
• and
• a second transport path surface disposed downstream of the nip means in the transport direction to face the transport means side of the nip means, the second transport path surface comprising a top portion protruding toward the transport means side beyond the nip line.
