ABSTRACT:
A paper feeder is capable of minimizing abnormal noise produced at a separation pad during paper feed, without reducing the paper feed capability, for use in an image forming apparatus using the same. Buffers are mounted on the separation pad. This arrangement ensures that, when a stick-slip condition occurs between the paper and separation pad during paper feed, and the separation pad is vibrated by the paper, the buffer vibrates so as to dissipate the vibration energy of the separation pad, with the result that the vibration of the separation pad is minimized, thereby to reduce any abnormal noise.
