摘要:
A negative charge controlling agent, wherein: the negative charge controlling agent comprises polycondensation product obtained by a polycondensation reaction of phenols and aldehydes; and the phenols comprises a (A) mononucleus phenolic compound which has one phenolic hydroxy group in which a hydrogen is bonded at the ortho position of a hydroxyl group of the phenolic hydroxy group and a (B) multinucleus phenolic compound which has at least two phenolic hydroxy groups in which a hydrogen is bonded at the ortho position of a hydroxyl group of each of the phenolic hydroxy group; and the content of the (B) phenolic compound in the phenols is 1 to 30 mol %.
