Abstract

Disclosed herein are an ink containing a self-dispersible pigment and a salt, wherein the self-dispersible pigment is a pigment to the surface of a particle of which a functional group containing at least a group having a hydrogen bonding property and two phosphonic acid groups is bonded, counter ions of the two phosphonic acid groups containing one of K<+>and NH<4>+ ; the salt is constituted by combining at least one cation of K<+>and NH<4>+ + with at least one anion selected from the group consisting of Cl<->, Br<->, I<->, ClO<->, ClO<2>- , ClO<3>- , ClO<4>- , NO<2>- , NO<3>- , SO<4>2- , CO<3>2- , HCO<3>- , HCOO<->, (COO<->)<2>, COOH(COO<->), CH<3>COO<->, C<2>H<4>(COO<->)<2>, C<6>H<5>COO<->, C<6>H<4>(COO<->)<2>, PO<4>3- , HPO<4>2- and H<2>PO<4>- ; a cation concentration in the ink is 0.04 mol/L or more; and the viscosity of a liquid obtained by evaporating 15% by mass of the ink is less than 3.5 mPa·s at 25°C.
