Patent ID: 8865302

Claim:
An electrophotographic recording medium, comprising: a base layer defining two surfaces; and a toner fixing layer covering at least on one of the two surfaces defined by the base layer, wherein the toner fixing layer comprises a hollow pigment, calcium carbonate and a binder resin, wherein the binder resin comprises polyvinyl alcohol and latex; wherein an amount of the hollow pigment in the toner fixing layer is in the range of about 10 to about 50 percent by weight based on total weight of the toner fixing layer, wherein an amount of calcium carbonate in the toner fixing layer is in the range of about 50 to about 70 percent by weight based on total weight of the toner fixing layer, wherein the toner fixing layer includes about 2 parts by weight of a polyvinyl alcohol, about 8 parts by weight of a latex, about 50-70 parts by weight of a calcium carbonate and about 20-40 parts by weight of the hollow pigment; wherein the toner fixing layer has a thickness greater than 25 μm and less than or equal to 40 μm; and wherein a ratio G p /G 0 is greater than 1.5, G 0 and G p representing white paper glossiness of the electrophotographic recording medium measured respectively before and after a performance of a printing operation on the electrophotographic recording medium.
