Document transporting device and image forming apparatus

An image forming apparatus comprising:

• a document transporting device including:
• a document accommodating section in which a document is accommodated;
• a transporting mechanism that transports the document accommodated in the document accommodating section along a transporting path;
• a feeding member that contacts with the document accommodated in the document accommodating section and feeds the document to the transporting mechanism by rotating;
• a rotation shaft that is driven to rotate and that rotatably supports the feeding member;
• an engaged portion that is formed at an end portion of the feeding member;
• a transmitting member that, by moving in an axial direction of the rotation shaft, can be located at a transmitting position where rotation of the rotation shaft is transmitted to the feeding member by an engaging portion of the transmitting member being engaged with the engaged portion, and at a releasing position where engagement between the engaged portion and the engaging portion is released;
• a moving member provided on the rotation shaft, that, upon relative rotating of the rotation shaft and the transmitting member, moves the transmitting member to the transmitting position and transmits the rotation of the rotation shaft to the transmitting member;
• and
• a resistor that contacts with an outer peripheral surface of the transmitting member and provides a resistance in a rotational direction to the transmitting member;
• a document reading section that reads image information of the document transported by the transporting mechanism of the document transporting device;
• and
• an image forming section that forms an image on a recording medium based on the image information read by the document reading section.
