Patent ID: 8534826

Claim:
An inkjet recording apparatus, comprising: a liquid ejection head which ejects an aqueous ultraviolet-curable ink toward a recording surface of a recording medium; a holding and drying unit including: a suction holding drum which conveys the recording medium on which an image has been formed by deposition of the aqueous ultraviolet-curable ink, while holding a back surface side of the recording medium reverse to the recording surface by suction through suction holes formed in an outer circumferential surface of the suction holding drum; and a hot air flow drying device which is disposed to face the outer circumferential surface of the suction holding drum; a transfer conveyance device which is arranged at a downstream side of the holding and drying unit and conveys the recording medium while holding a leading end of the recording medium and curving the back surface side of the recording medium in a convex shape; and a fixing unit including an ultraviolet light irradiation device which is arranged at a downstream side of the transfer conveyance device and irradiates ultraviolet light onto the image formed on the recording surface of the recording medium, wherein intervals between the suction holes increase, whereby an opening ratio of the suction holes decreases, from a center part of a region of the outer circumferential surface corresponding to the recording medium, toward end parts of the region, wherein the intervals between the suction holes increase from the center part of the region of the outer circumferential surface corresponding to the recording medium, toward the end parts of the region in a width direction of the recording medium, and wherein edge portions of the suction holes have grooves of figures similar to the suction holes and larger than the suction holes.
