An image forming apparatus which includes an ejecting unit which ejects liquid cured by being irradiated with light onto a medium for printing, an irradiation unit which irradiates the liquid which has landed onto the medium for printing with the light, and an image quality inspection unit which inspects an image quality of an image which is formed on the medium for printing, in which, when the image quality inspection unit detects abnormal formation of the image, an intensity of the light of the irradiation unit is controlled.

Image forming apparatus

An image forming apparatus includes: a first head that discharges first light-curable ink; a light radiating unit that is positioned at one side from the first head in a predetermined direction and cures the first light-curable ink by radiating light to the first light-curable ink; a second head that is positioned at the one side from the light radiating unit in the predetermined direction and discharges second light-curable ink; and a control unit that causes an image to be formed on a medium by controlling the first head and the second head to discharge the light-curable ink while moving the position of the medium relative to the first head, the light radiating unit, and the second head to the one side in the predetermined direction.

An image recording apparatus includes: a nozzle that discharges electromagnetic wave curable ink that is cured when an electromagnetic wave is irradiated onto a recording medium; and an irradiator for irradiating the electromagnetic wave, wherein a filter that transmits the electromagnetic wave is provided on the irradiator, and the filter has a first transmittance that causes the electromagnetic wave curable ink on the recording medium to be curable with respect to an electromagnetic wave that is incident at a first angle and a second transmittance that maintains a state in which the nozzle can discharge the electromagnetic wave curable ink with respect to an electromagnetic wave that is incident at a second angle.
