PURPOSE: To obtain recording paper, excellent in toner fixing properties and printed density, having preventing effects on discoloration of images and useful for electrophotographic transfer paper, etc., by applying a specific fluorescent brightener and a specified penetrant onto base paper, containing CaCO3 and having a specific Stoeckigt sizing degree.

CONSTITUTION: The objective recording paper is obtained by adding light precipitated calcium carbonate, aluminum sulfate, amphoteric starch and a sizing agent to pulp such as beaten LBKP or NBKP, forming paper with a Fourdrinier type paper machine, etc., providing base paper having 15-25sec Stoeckigt sizing degree, then applying a fluorescent brightener expressed by the formula in a coating amount of 0.2-1.0g/m2 onto the base paper and at least one of a nonanol-based penetrant or a nonylphenol-based penetrant in a coating amount of 0.001-0.03g/m2, drying the coated paper and carrying out the machine calendering treatment so as to provide 80sec Bekk smoothness. This recording paper is useful as an electrophotographic transfer paper excellent in toner fixing properties and ink jet recording paper having a high printed density without unevenness of density, etc.
