摘要

An ink contains at least a pigment, wherein the pigment is C.I. Pigment Red 282, and a primary particle diameter D (nm) of the pigment and a 50%-cumulative diameter D50 (nm) in particle diameter distribution of the pigment satisfy a relation of D×0.95≦̸D50≦̸150, and a 90%-cumulative diameter D90 (nm) in particle diameter distribution of the pigment and the 50%-cumulative diameter D50 (nm) satisfy a relation of 1.5≦̸D90/D50≦̸2.5.
