(57) [Summary] [Problem] To use a UV light source suitable for an ink jet recording method, Provided are a black ink capable of forming an image having high density, high sensitivity and good adhesion to a substrate, and an image forming method using the same. SOLUTION: A black ink curable by irradiation of energy rays is jetted to a base material by an inkjet method, Next, in an ink jet recording black ink that forms an image by irradiating an energy ray from the ink ejection surface side, the ink comprises a color material that reproduces at least black and a photopolymerization initiator having a photosensitive wavelength in the ultraviolet, A transmission density corresponding to a solid image at 360 nm is such that the component other than the photopolymerization initiator in the ink is 1.30 or less, and the photopolymerization initiator component in the ink is 0.15 or more. Black ink for inkjet recording. |
