Recording material transporting device and image reading apparatus comprising first and second reading units, using an endless transport belt having an inner peripheral surface with a greater coefficient of friction than an outer peripheral surface and generating airflow to bring the recording material in close contact with the transport belt

An image reading apparatus comprising:

• an image sensor that reads an image formed on a recording material;
• a transport belt having an endless shape and having an inner peripheral surface and an outer peripheral surface which is on an opposite side of the inner peripheral surface and the entire outer peripheral surface having a friction coefficient smaller than a friction coefficient of the entire inner peripheral surface, the transport belt transporting a recording material by using the outer peripheral surface toward the image sensor;
• and
• a driving roller that rotates while being in contact with the inner peripheral surface of the transport belt and that rotatably drives the transport belt
• a fan that generates airflow flowing from an outer periphery of the transport belt toward an inner periphery of the transport belt to bring a recording medium into close contact with the outer peripheral surface of the transport belt facing the image sensor;
• and
• a transport roller that is disposed upstream of the transport belt in a recording material transport direction and that transports a recording material toward the transport belt, wherein a force applied to a recording material due to the friction coefficient of the outer peripheral surface of the transport belt and due to a force generated by the fan to bring the recording material into close contact with the transport belt is smaller than a force of the transport roller to transport the recording material.
