Abstract:
The present invention relates to an image forming method and an image forming apparatus by an inkjet method using a gel ink, which minimize a gloss difference between an image-formed region and an image-less region, regardless of a type of a paper substrate used. The image forming method of the present invention is a method for forming an image on a paper substrate by using an inkjet ink that undergoes a temperature-induced sol-gel phase transition. The image forming method includes: a step of subjecting a paper substrate to a corona discharge treatment; a step of ejecting liquid droplets of inkjet ink and landing the droplets on a surface of the paper substrate subjected to the corona discharge treatment; and a step of irradiating the droplets of the inkjet ink landed on the paper substrate with an actinic light ray to cure the inkjet ink.

Claim (Index 7):
An image forming apparatus comprising:\n a corona discharge treatment section that modifies a surface of a recording medium; an inkjet head having a nozzle face, on which an ejection port of a nozzle is provided, the nozzle being capable of ejecting droplets of an inkjet ink which contains a photocurable compound and a gelling agent having no polymerizable group and which undergoes temperature-induced sol-gel phase transition; a conveying section that conveys the recording medium at a position which is in vertical direction and directly below the ejection port of the nozzle of the inkjet head, so as to move the recording medium opposite to the inkjet head; an irradiation section that irradiates an upper face of the conveying section with actinic radiation from a light source; and a control section that controls the corona discharge treatment section, the inkjet head, the conveying section and the irradiation section; wherein the recording medium is a paper substrate, and the corona discharge treatment section performs a surface treatment of a paper substrate having a 60\u00b0 gloss value of 5 or more and 50 or less.
