Patent ID: 7712887

Claim:
An image forming apparatus comprising: a first liquid ejection device which, while scanning to and fro in a direction substantially orthogonal to a conveyance direction of a recording medium, ejects a first liquid containing a coloring material onto the recording medium; second liquid ejection devices which are disposed respectively on both regions in a scanning direction outside the first liquid ejection device, the second liquid ejection devices ejecting a second liquid not including a coloring material onto at least an area of the recording medium on which the first liquid is to be deposited prior to the first liquid being deposited while the second liquid ejection devices perform a scan together with the first liquid ejection device; and first radiation irradiating devices which are disposed respectively on both regions in the scanning direction outside the first liquid ejection device, the first radiation irradiating devices irradiating an area of the recording medium on which the first liquid and the second liquid have been deposited with a radiation while the first radiation irradiating devices perform a scan together with the first liquid ejection device, wherein one of the first liquid and the second liquid contains a radiation-curable polymerizable compound and does not contain a polymerization initiator; and the other of the first liquid and the second liquid contains the polymerization initiator and does not contain the radiation-curable polymerizable compound.
