Abstract
A recording medium including a substrate and an ink receiving layer on the substrate, the ink receiving layer containing inorganic particles and a water-soluble resin. The recording medium has an HM1 of 40 N/mmor less and has a rate of change of HM2 to HM1 of 400% or less. HM1 is a Martens hardness when an indenter is pushed at a 500 mN load over 180 seconds from a surface of the recording medium into a 1 μm depth in a thickness direction thereof. HM2 is a Martens hardness when the indenter is pushed up to a position where the indenter is not in contact with the surface and is then pushed at a 500 mN load over 180 seconds from a pressing starting position into a 1 μm depth in the thickness direction at the same point as that at which the indenter is first pushed.
