Image formation apparatus

摘要

An image formation apparatus includes a liquid droplet adhesion unit which makes a first and second type of liquid droplet adhere to a recording medium, an irradiator which irradiates electromagnetic waves individually onto the droplets, an irradiation controller which makes the irradiator irradiate the electromagnetic waves periodically, and a frequency setting unit which sets a frequency of an irradiation period to a first frequency such that surface glossiness of the first-type liquid droplet is equal to or higher than a predetermined threshold value, and sets a frequency of the irradiation period to a second frequency which is different from the first frequency such that surface glossiness of the second-type liquid droplet is lower than the threshold value.

1. An image formation apparatus comprising:
a liquid droplet adhesion unit which makes a first-type liquid droplet and a second-type liquid droplet adhere to a recording medium, the first-type liquid droplets being adhered to the recording medium after the second-type liquid droplet; a first irradiation controller which controls an irradiator to cause the irradiator to irradiate electromagnetic waves onto the first-type liquid droplet at a first frequency periodically; and a second irradiation controller which controls an irradiator to cause the irradiator to irradiate electromagnetic waves onto the second-type liquid droplet, wherein when the second-type liquid droplet is adhered to the recording medium, the second irradiation controller makes the irradiator irradiate the electromagnetic waves at a first second frequency periodically, and wherein when the second-type liquid droplet is not adhered to the recording medium, the second irradiation controller makes the irradiator irradiate the electromagnetic waves at the first frequency periodically, wherein a surface glossiness of the first-type liquid droplet onto which the electromagnetic waves are irradiated by the first irradiation controller is equal to or higher than a predetermined threshold value, and wherein a surface glossiness of the second-type liquid droplet onto which the electromagnetic waves are irradiated by the second irradiation controller is lower than the threshold value.
