Abstract

A recording-medium feeding device feeds a recording medium by separating loaded recording media sheet by sheet. An air outlet (118) blows air to the recording media from a lateral side with respect to a direction of feeding the recording-medium. The air outlet (118) is formed cross a recording-medium feeding plane, such that an upper edge in an upstream of the recording-medium feeding direction is higher than an upper edge in a downstream of the recording-medium feeding direction.
