Abstract
An active energy ray curable composition includes an inorganic pigment and a polymerizable monomer, wherein the inorganic pigment is carbon black having a ratio of the amount of hydrophilic functional group to the specific surface area in a range of from 7 μmol/mto 42μmol/mor a metal oxide having a ratio of the amount of sulfonic acid group to the specific surface area in a range of from 7 μmol/mto 85 μmol/m, wherein the active energy ray curable composition has a viscosity change rate (ΔV) represented by the following relation 1 from −10 percent by mass to +10 percent by mass:Δ(%)=|×100  relation 1,
