摘要：
When two or more sheets of paper P are fed in an overlapped manner to a nip where a paper feed roller and a separation roller are in pressure contact with each other, a sub-CPU of a sheet feeding unit rotates the paper feed roller in a paper feeding direction and rotates the separation roller in a direction opposite to the feeding direction, so as to separate overlapping, and thereafter, it rotates the paper feed roller and the separation roller again in the feeding direction.
