There is provided an inkjet recording ink and recording media set, which contains: an inkjet recording ink; and a recording medium, wherein the inkjet recording ink comprises at least: water; a water-soluble organic solvent; and a colorant containing carbon black, and having a volume average particle diameter of 40 nm to 100 nm, wherein the recording medium contains: a substrate; and a coating layer on at least one side of the substrate, and wherein an amount of pure water transferred to the recording medium, as measured with a dynamic scanning absorptometer at 23 C and 50% RH, at a contact time of 100 ms is 2 ml / m2 to 35 ml / m2 while an amount of pure water transferred to the recording medium at a contact time of 400 ms is 3 ml / m2 to 40 ml / m2.

An image forming apparatus has a first recording mode of outputting the recording material without passing thru the glossiness applying device after fixing and a second recording mode using the glossiness applying device, and then outputting the recording material. In the latter recording mode (B), when a void ratio G of toner in the toner image not yet subjected to the glossing process by the glossiness applying device is defined by a thickness t1 of a toner layer on the recording material after fixing and before entering the glossiness applying device, and a thickness t2 of a toner layer on the recording material after passing through the glossiness applying device, satisfies the formula: G=100×(t1-t2) / t1. In the recording mode (B), fixing conditions for the fixing device and the glossiness applying device are respectively set so that the void ratio of toner satisfies a formula 15≦G≦60.

A toner for developing a latent electrostatic image including a base of toner particle which contains a binder resin and a coloring agent, and an external additive. Herein, a plurality of the base of toner particle has a volume average particle diameter (Dv) of 3 μm to 7 μm, a ratio (Dv / Dn) of the volume average particle diameter (Dv) to a number average particle diameter (Dn) is 1.01 to 1.25, a plurality of the base of toner particle contains 15% by number or less of the base of toner particle having a particle diameter of 0.6 μm to 2.0 μm, a plurality of the base of toner particle has a circularity of 0.930 to 0.990 on average, the binder resin contains a modified polyester resin, and the toner contains 0.3 parts by weight to 5.0 parts by weight of the external additive, relative to 100 parts by weight of the base of toner particle.

An ink jet recording apparatus of the present invention includes a head, a first light source, a second light source. Liquid droplets of a photo-curable ink composition are applied to a recording medium. After one second or less elapses from the time when the liquid droplets are applied to the recording medium, the liquid droplets are illuminated with light of the first light source. After 0.1 second or more and one second or less elapses from the time when the liquid droplets are illuminated with light of the first light source, the liquid droplets are illuminated with light of the second light source.

The invention provides an ink composition, which is improved in dispersibility and fastness properties and is excellent in dispersion stability and re-solubility owing to dispersed particles in which a coloring material is included by a crosslinked hydrophobic block segment in a dispersing polymer. The ink composition contains an amphiphilic block polymer compound, in which a coloring material is included, and a medium, wherein the amphiphilic block polymer compound, in which the coloring material is included, forms a dispersed particle having the hydrophobic block segment as an internal core part, and the hydrophobic block segment is crosslinked.

There is provided an inkjet printing method of applying plural different kinds of color ink containing pigment as a coloring agent and clear ink not containing the coloring agent on a print medium to form an image thereon. An amount of the clear ink applied in a unit area of the print medium is adjusted based upon an amount of each of the plural kinds of the color ink applied in the unit area. Since the amount of the clear ink is adjusted based upon not only the amount but also the kind of the color ink applied in the unit area, the clear ink application amount to each unit area can be more appropriate to largely reduce the gloss variations.

An image-fixing method contains: passing a recording medium bearing an image through a nip between two or more fixing members to fix the image onto the recording medium; and ejecting the recording medium along with the fixing member contacting with a non-image-bearing surface of the recording medium, wherein the fixing member contacting with an image-bearing surface of the recording medium has a lower surface hardness than that of the fixing member contacting with the non-image-bearing surface, the image is comprised of a toner containing toner particles, each toner particle contains wax having an aliphatic hydrocarbon chain, and polyester resin having an aromatic ring, a total amount of the wax in the toner particle is 1 to 20 mass %, determined by DSC, an amount of the wax located in the specific region of the toner particle is 0.05 to 0.40 that is an intensity ratio (P2850 / P828) determined by FTIR-ATR, and the wax is partially or entirely encapsulated in the toner particle as dispersed particles.

Provided is an ink jet ink capable of recording an image having an unprecedentedly high level of scratch resistance and excellent glossiness while satisfying reliability of the ink such as ejection stability. The ink jet ink contains at least a pigment and a graft polymer, and is characterized in that the graft polymer includes at least a specific nonionic unit and a unit having a polysiloxane structure.
