Abstract
The invention provides a recording medium capable of inhibiting conspicuousness of scratches attached to the recording medium and preventing the occurrence of density unevenness in an image. The recording medium has a substrate and an ink receiving layer provided on the substrate, wherein substrate is a resin-coated substrate obtained by coating a base material with a resin, and wherein Ra2 is 0.3 μm or more and 2.5 μm or less and Ra1−Ra2 is 2.0 μm or more, where Ra1 is an arithmetic average roughness of a surface of the substrate son the side of the ink receiving layer as prescribed by JIS B 0601:2001 and Ra2 is an arithmetic average roughness of the outermost surface of the recording medium as prescribed by JIS B 0601:2001.
