ABSTRACT:
A paper feeding mechanism for an image forming apparatus includes a drive roller rotated by a first shaft driven by a motor. A press roller is supported by a second shaft which is parallel to and spaced apart from the first shaft. The press roller is pressed against the drive roller, and is driven by the drive roller. A cam pushes the second shaft (and therefore the press roller) away from the drive roller to prevent unnecessary external forces from being exerted on paper being fed through the rollers. The cam is actuated by clutching means for transferring rotating force of the first shaft to the cam to rotate the cam when it is necessary to move the press roller away from the drive roller.
