1. An ink-jet recording apparatus for recording on a recording sheet with an ink containing at least a pigment, a resin, and water, the ink-jet recording apparatus comprising:
at least two color inkjet heads,
wherein the at least two color inkjet heads are arranged in a conveyance direction of the recording sheet, and
the color inkjet head that discharges the ink containing resin-encapsulated pigment particles with a largest number average particle diameter among the at least two color inkjet heads is arranged in a most downstream of the conveyance direction of the recording sheet.
2. The ink-jet recording apparatus according to claim 1, comprising
at least three color inkjet heads,
wherein the larger the number average particle diameters of the resin-encapsulated pigment particles contained in the inks discharged from the at least three color inkjet heads are, the more downstream side the color inkjet heads are arranged in the conveyance direction of the recording sheet.
3. The ink-jet recording apparatus according to claim 1,
wherein the recording sheet has a recording surface to be brought into contact with a conveyance roller after the ink discharge.
4. The ink-jet recording apparatus according to claim 1,
wherein the inkjet head includes a long inkjet head.
5. The ink-jet recording apparatus according to claim 1, further comprising
a black inkjet head.
6. An ink set for inkjet recording, comprising:
inks of at least two colors other than a black,
wherein a difference between the number average particle diameters of the resin-encapsulated pigment particle in the inks of the at least two colors is equal to or more than 30 nm under a combination of the inks for a maximum difference.
7. A method for inkjet recording on a recording medium by discharging an ink containing at least a pigment, a resin, and water, the method comprising:
when discharging the inks of at least two colors other than a black successively in order, lastly discharging the ink containing the resin-encapsulated pigment particle with a largest number average particle diameter among the inks of at least two colors.
8. The method according to claim 7, wherein
when discharging the inks of at least three colors other than the black successively in order, the more downstream the inks of at least three colors are discharged in the conveyance direction of the recording sheet, the larger the number average particle diameters of the resin-encapsulated pigment particles contained in the discharged inks become.
