Zusammenfassung:	PROBLEM TO BE SOLVED: To provide paper which shows a high filler retention yield in paper manufacturing and has a high ash content and good strength and a sizing property and, especially, to provide paper having a high surface filling effect when coating starch or a coating material by a size press and/or an on-machine coater due to the good sizing property thereof.SOLUTION: The pretreatment comprises adding a copolymer to a filler before addition to paper stock and mixing the two, the copolymer having intramolecular hydrophobic groups and further carboxyl group structures with high affinity to calcium, which is preferably a styrene/acryl-based copolymer. By adding this pretreated filler to the paper stock and manufacturing paper, the filler retention yield could be improved, and paper having high ash content and good strength and a sizing property could be obtained.
